Electric Bulb Calculation:

- Given: Voltage (V) = 220 V, Resistance (R) = 1200 ohm
- Using Ohm's Law: Current (I) = V/R
- Substituting the values: I = 220/1200
- Therefore, the current drawn by the electric bulb is I = 0.1833 A

Heater Calculation:

- Given: Resistance (R) = 100 ohm
- Using Ohm's Law: Current (I) = V/R
- Substituting the values: I = 220/100
- Therefore, the current drawn by the heater is I = 2.2 A

Explanation:

- The current drawn by an electrical device is directly proportional to the voltage and inversely proportional to the resistance.
- In the case of the electric bulb, with a higher resistance of 1200 ohms, it draws a lower current of 0.1833 A from the 220 V source.
- On the other hand, the heater with a lower resistance of 100 ohms draws a higher current of 2.2 A from the same 220 V source.
- This difference in current drawn is due to the varying resistance of the devices, as per Ohm's Law.
- It is important to consider the resistance of the device when calculating the current drawn from a voltage source.
