Question

If an electric circuit has 30ohms and 10amps. How many volts the battery voltmeter should read?

Answer 1

Answer:

The battery voltmeter should read 300 Volt

Explanation:

Ohm's Law

It states that the current through a conductor is directly proportional to the voltage applied to it and inversely proportional to the resistance of the conductor. This relationship can be written as

$\displaystyle I=\frac{V}{R}$

Solving for V

V=IR

The electric circuit has a resistance of 30 ohms and carries a current of I=10 A, thus the voltage is:

V = 10 A * 30 Ohm

V = 300 Volt

The battery voltmeter should read 300 Volt
