Question

What is the current through a 5 ohm resistor if the voltage across it is 100V

Answer 1

Answer:

Explanation:v=ir

100=5i

I=20

Answer 2

Answer:

Given:

Resistance (R)= 5 Ω

Voltage (V) = 100 V

To Find:

Current ($\rm I$) through 5 Ω resistor

Solution:

We know that,

$\boxed{\rm V = I \times R}$

Here,

We are asked to calculate current

Hence, the formula to be used is

$\boxed{\rm I = \dfrac{V}{R} }$

By Substituting the above values in the formula

We get,

$\rm \implies I = \dfrac{100}{5}$

$\rm \implies I = 20\;Amperes$

Hence,

Current ($\rm I$) through 5 Ω resistor is 20 A
