Question

Taking what you have learned about Ohm's law what would the current be through a circuit if the power supply was 110 v and the total resistance on the circuit was found to be 15.2 kiloOhms?

Answer 1

7.24 mA

Step-by-step explanation:

Ohm's law states that the current passing through two points is directly proportional to the voltage across the two points.

V ∝ I

V = IR

R is the resistance which is the constant of proportionality, V is the voltage and I is the current.

Given that V = 110 V, R = 15.2 kΩ

Therefore using ohms law, we calculate the current as:

`V=IR\\\\I=(V)/(R)\\\\I=(110)/(15.2*10^3)\\\\I=7.24*10^(-3)\\\\I=7.24\ mA`
