Question

The Voltage difference of a circuit is 16V and the resistance is 120 ohms. What is the current in the circuit? Show me your work please!

Answer 1

Answer:

0.133 A

Explanation:

Given:

The voltage difference is, $V=16\ V$

The resistance of the circuit is, $R=120\ ohms$

Now, as per Ohm's Law, the potential difference across two points in a circuit is directly proportional to the current supplied in the circuit. The constant of proportionality is the resistance of the circuit.

Hence, the mathematical statement of Ohm's law is given as:

$V=IR$ Where $I$ is the current in the circuit.

Now, plug in 16 for 'V' and 120 for 'R' and solve for 'I'. This gives,

$16=120I\\I=\frac{16}{120}\\I=0.133\ A$

Therefore, the current in the circuit is 0.133 amperes.
