How to Calculate Lamp's Resistance with Given Voltage and Current
What is the equation to find out the resistance of a lamp connected to a 24 volt battery with a current of 3 amps flowing through it?
a. R = V/I
b. V = IR
c. I = V/R
Answer:
The correct equation to find out the resistance of a lamp connected to a 24 volt battery with a current of 3 amps flowing through it is: R = V/I
To calculate the resistance of the lamp, you can use the formula R = V/I. In this case, the voltage V is 24 volts and the current I is 3 amps. By substituting these values into the formula, you get:
R = 24 volts / 3 amps
R = 8 ohms
Therefore, the resistance of the lamp is 8 ohms when a current of 3 amps flows through it and it is connected to a 24 volt battery.
