**Amps**. To use the chart, cover up the V with your finger and use the remaining chart**calculation**of W divided by A. Using our sample panel data, 60 watts divided 5**Amps**equals 12 Volts. The formula for**Amps**is Watts divided by Volts.3

## What are the rules for resistance in a series circuit?

Resistor in

**series**. When resistors are connected in**series**, the current through each resistor is the same. In other words, the current is the same at all points in a**series circuit**. The total**resistance**of a number of resistors in**series**is equal to the sum of all the individual resistances.4

## How do you calculate watts?

To determine the

**wattage**, use a simple multiplication formula. The ampere (or amps) is the amount of electricity used. Voltage measures the force or pressure of the electricity. The number of**watts**is equal to amps multiplied by volts.5

## How do you calculate the total resistance of a series circuit?

Voltage is the same across each component of the parallel

**circuit**. The sum of the currents through each path is equal to the**total**current that flows from the source. You can**find total resistance**in a Parallel**circuit**with the following**formula**: 1/Rt = 1/R1 + 1/R2 + 1/R3 +6

## What is series resistance?

Definition :- Imagine two or more resistors in

**series**, i.e. connected one after another so that the same current flows through them. The total**resistance**of the collection is the sum of individual**resistances**.7

## How do you calculate the charge?

**Charge**, current and time. Electrical

**charge**is measured in coulomb (C). The amount of electrical

**charge**that moves in a circuit depends on the current flow and how long it flows for. For example, if a current of 10 A flows for 30 s, then 10 x 30 = 300 coulombs of electrical

**charge**moves.

## Is Ohm's law?

**Ohm's law**states that the current through a conductor between two points is directly proportional to the voltage across the two points.

9

## What is the formula of resistance?

The resistance R in ohms (Ω) is equal to the

**voltage**V in volts (V) divided by the current I in**amps**(A): Since the current is set by the values of the**voltage**and resistance, the Ohm's law formula can show that: If we increase the**voltage**, the current will increase.10

## How do you find the resistance?

Insert these values into Ohm's Law. Rearrange V = IR to solve for

**resistance**: R = V / I (**resistance**= voltage / current). Plug the values you found into this formula to solve for total**resistance**. For example, a series circuit is powered by a 12 volt battery, and the current is measured at 8 amps.11

## How do you calculate the total current?

**Part 2**

**Finding Total Current of a Series Circuit Connection**

- Find the total resistance of the circuit.
- Identify the total voltage of the resistor.

## How do you find current in a series circuit?

**UNDERSTANDING & CALCULATING SERIES CIRCUITS BASIC RULES**

- The same current flows through each part of a series circuit.
- The total resistance of a series circuit is equal to the sum of individual resistances.
- Voltage applied to a series circuit is equal to the sum of the individual voltage drops.

## What is the total equivalent resistance of the circuit?

More

**resistance**means less current is flowing through the**circuit**.**Equivalent resistance**is a different way of indicating '**total**'**resistance**, which we calculate differently for series and parallel circuits. In a series**circuit**, the different components are connected in a single, continuous loop.14

## What is the measure of resistance?

Resistance is the measure of difficulty electrons have in flowing through a particular object. It is similar to the friction an object experiences when moving or being moved across a surface. Resistance is measured in ohms;

**1 ohm**is equal to 1 volt of electrical difference per 1 ampere of current.15

## What is the formula for power?

The standard metric unit of power is the Watt. As is implied by the

**equation**for power, a unit of power is**equivalent**to a unit of work divided by a unit of time. Thus, a Watt is**equivalent**to a Joule/**second**.16

## What is the difference between a series and a parallel circuit?

**In a series circuit**, the current through each of the components is the same, and the voltage across the

**circuit**is the sum of the voltages across each component.

**In a parallel circuit**, the voltage across each of the components is the same, and the total current is the sum of the currents through each component.

17

## What is the Ohm's law?

The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R.

**Ohm's Law**is given by: V = I R where V is the potential difference between two points which include a resistance R.18

## How do you find voltage drop?

To calculate the

**voltage drop**across a resistor, remember: Ohm's Law (V=I*R) is your friend.**Find**the current flowing through a resistor, then multiply the current in amps by resistance in ohms to**find**the**voltage drop**in volts.19

## How does the length of a resistor affect resistance?

**Resistance**increases with

**length**because the electrons have further to go, so suffer greater collisions with atoms in the material. Look at these wires: Electrons moving through the short wire only feel

**resistance**for a short time compared to the longer one. This means its

**resistance**is less.

## What is a resistor and what does it do?

A

**resistor**is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits,**resistors**are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
