Question

Calculate the electric current passing through the circuit when the key is closed is 5×2=10v and 5ohm,10ohm,15ohm is

Answer 1

Answer;

2 amp, 1 amp and 0.66 amp

Explanation:

To solve the problem, we would be using Ohm’s law and considering a circuit with two voltage sources connected in series with one resistor. Formula for calculating current will be;

I = V / R;

Case 1;

Here V = 10 volts

Resistance = 5 ohms

I = 10 / 5;

I = 2 amp

Case 2;

Here V = 10 volts

Resistance = 10 ohms

I = 10 / 10;

I = 1 amp

Case 3;

Here V = 10 volts

Resistance = 15 ohms

I = 10 / 15;

I = 0.66 amp
