A bulb draw a current of three amperes from a 30 volt battery calculate the resistance that the bulb affers to the flow of current
To calculate the resistance offered by the bulb, you can use Ohm's Law, which states that the resistance (R) of a circuit is equal to the voltage (V) divided by the current (I):
R = V / I
In this case, the voltage (V) is given as 30 volts, and the current (I) is given as 3 amperes.
Substituting these values into the formula, we get:
R = 30 volts / 3 amperes
Therefore, the resistance offered by the bulb is:
R = 10 ohms.
