Question

An electric heating element has a resistance of 16 Ω and is connected to a voltage of 120 V. How much current will flow in this circuit?a) I=E/Rb) I=120/16c) I=7.5 A

Answer 1

This is weird.

All three 'choices' are true.

Line um up. (a) shows how to solve the problem. (b) does it. and (c) is the answer.

Answer 2

Ohm's law states that the voltage across a conductor is directly proportional to the current flowing in it. The current flowing in the circuit is 7.5 ampere.

Given information-

An electric heating element has a resistance of 16 Ω .

The voltage of the element is 120 V.

The flowing current for a element with the voltage and resistance known can be find out using the Ohm's law.

What is Ohm's law?

Ohm's law states that the voltage across a conductor is directly proportional to the current flowing in it. Thus,

$V\propto I\\V=IR$

Here, $R$ is the resistance of the conductor.

The current flowing in the electric hitting element in which the voltage is 120 V and resistance is 16 Ω is,

$120=I\times16$

Solve for I,

$I=\dfrac{120}{16} \\I=7.5$

Hence the current flowing in the circuit is 7.5 ampere.
