Question

How much current will an electric bulb draw from a 220v source, if the resistance of the bulb filament is 1200π? (B) how much current will an electric heater coil draw from a 220v source l, if the resistance of the heater coil is 100π?

Answer 1

The current drawn by the electric bulb from a 220V source can be calculated using Ohm's Law, while the current drawn by the electric heater coil with a resistance of 100π can also be calculated using Ohm's Law.

Step-by-step explanation:

The current drawn by an electric bulb from a 220V source can be calculated using Ohm's Law. Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied and inversely proportional to the resistance of the conductor.

To calculate the current, we can use the formula:

Current (I) = Voltage (V) / Resistance (R)

For the electric bulb with a filament resistance of 1200π, the current can be calculated as:

I = 220V / 1200π

To calculate the current drawn by an electric heater coil with a resistance of 100π, we can again use Ohm's Law:

I = 220V / 100π

By solving these equations, we can find the values of current drawn by both the electric bulb and the electric heater coil.
