Question

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

Answer 1

Answer:

Voltage = 300 Volts

Explanation:

Given the following data;

Resistance = 30 Ohms

Current = 10 Amps

To find voltage;

Ohm's law states that at constant temperature, the current flowing in an electrical circuit is directly proportional to the voltage applied across the two points and inversely proportional to the resistance in the electrical circuit.

Mathematically, Ohm's law is given by the formula;

$V = IR$

Where;

• V represents voltage measured in voltage.

• I represents current measured in amperes.

• R represents resistance measured in ohms.

Substituting into the equation, we have;

$V = 10 * 30$

Voltage = 300 Volts.

Therefore, the battery voltmeter should read 300 Volts.
