Question

A potential difference of 18 V is applied to a resistor whose resistance is 240 Ω . What is the current that flows through the resistor?

Answer 1

Answer:

0.075A

Explanation:

V = IR

where V - voltage, I - current, R - resistance

Hence, 18 = I * 240

I = 18/240

I = 0.075A

Answer 2

Answer: I = 0.075 A

Explanation: According to Ohm's Law Voltage is equal to the product of current and resistance or V= IR.

Derive for current I, I = V/R

I = V/R

= 18 V / 240 ohms

= 0.075 A
