An electrical discharge of 50 cells passed through a conductor with a resistance of 10 ohms in 1 minute.

An electrical discharge of 50 cells passed through a conductor with a resistance of 10 ohms in 1 minute. find the voltage applied to the ends of the conductor.

Given:

R = 10 Ohm – conductor resistance;

t = 1 minute = 60 seconds – time span;

q = 50 Coulomb is the electric charge that passed through the conductor during the time interval t.

It is required to determine U (Volt) – the voltage applied to the ends of the conductor.

Let’s find the strength of the current that passed through the conductor:

I = q / t = 50/60 = 5/6 = 0.8 Amperes (the result is rounded to one decimal place).

Then the voltage will be equal to:

U = I * R = 0.8 * 10 = 8 Volts.

Answer: a voltage of 8 volts is applied to the ends of the conductor.
