Question

An ammeter measures that the current in a simple circuit is 0.22 amps. The circuit is connected to a 55V battery. What is the resistance in the circuit?

Answer 1

Answer: The resistance in the circuit is 250 ohms

Step-by-step explanation:

According to Ohm's law:

`V=IR`

where V = voltage = 55 V

I = current in Amperes = 0.22 A

R = Resistance = ?

Putting in the values we get:

`55V=0.22A* R`

`R=250ohm`

Thus the resistance in the circuit is 250 ohms
