Electricity: Calculating Energy Transfer by Components (DONE)

Question 1

A question from last deck.

Answer 1

Question 2

Whenever charge flows in a circuit work is done in other words energy is transferred.

What is the equation for energy transferred?

Answer 2

Question 3

Calculate the total energy transferred?

Answer 3

Question 4

Answer 4

First we need to find the P.D of resistor A we can do this by doing the subtraction 30-25 which is 5V. As the P.D in a series circuit adds up.

To calculate the energy transferred by resistor A we need to multiply the charge flow (3C) by the P.D (5V) this gives us an energy transfer of 15J
