Answer:
The resistance of the bulb is 1000 ohms.
Explanation:
What is the resistance of a bulb that is connected to a 20 v source through which a current of 20 mA passes
We have,
Voltage of the bulb is 20 V and the current passes is 20 mA.
It is required to find the resistance of the bulb. The relation between resistance, current and voltage is given by using Ohm's law as :
V = IR
R is resistance

So, the resistance of the bulb is 1000 ohms.
