A 5 ohm resistor a 20 ohm resistor and a 25 ohm resistor are all connected in series to a 100 volt power source What is the current running through the circuit?

To find the current running through the circuit, you need to use Ohm's Law, which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, and inversely proportional to the resistance between them.

You can use the following formula to calculate the current:

I = V / R

Where I is the current, V is the voltage, and R is the resistance.

In this case, the total resistance of the circuit is the sum of the individual resistances, which is 5 ohms + 20 ohms + 25 ohms = 50 ohms.

Therefore, the current flowing through the circuit is:

I = 100 volts / 50 ohms = 2 amps.
