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?

Sagot :

Answer: The resistance in the circuit is 250 ohms

Explanation:

According to Ohm's law:

[tex]V=IR[/tex]

where V = voltage  = 55 V

I = current in Amperes = 0.22 A

R = Resistance = ?

Putting in the values we get:

[tex]55V=0.22A\times R[/tex]

[tex]R=250ohm[/tex]

Thus the resistance in the circuit is 250 ohms
