What is the voltage on the section of the circuit with resistance R = 25 Ohm at current strength I = 100mA?

Given:

R = 25 Ohm – resistance of the section of the electrical circuit;

I = 100 milliamperes is the current flowing through the circuit.

It is required to determine U (Volt) – the voltage at the section of the electrical circuit.

Let’s translate the current strength into SI units:

I = 100 mA = 100 * 10 ^ -3 = 0.1 Ampere.

Then, according to Ohm’s law, the voltage on the circuit section will be equal to:

I = U / R, hence:

U = R * I = 25 * 0.1 = 2.5 Volts.

Answer: the voltage in the section of the electrical circuit is 2.5 volts.
