Question

If 12V battery maintains a 4.5A current through a resistor what is the resistance of the resistor?

Answer 1

2.7ohms

Step-by-step explanation:

Given parameters:

Voltage of the battery = 12V

Current = 4.5A

Unknown:

Resistance of the resistor = ?

Solution:

From Ohm's law, we know that;

V = IR

V is the voltage

I is the current

R is the resistance

So;

R =
`(V)/(I)` =
`(12)/(4.5)` = 2.7ohms
