Question

What is the current through a 4 ohms resistor if the voltage across it is 8v

Answer 1

Answer:-

2A

Given:-

Resistance, r = 4 ohm

Voltage, v = 8v

Formula used:-

$current = \frac{voltage(r)}{resistance(r)}$

Solution:-

We have,

r = 4 ohm

v = 8v

therefore,

$current = \frac{8}{4} = 2 \: ampere$

Hence, The Current across the resistor is 2A
