- Potential Difference ,V = 220V
- Resistance ,R = 1200Ω
- Resistance of Heater Coil = 100Ω
- Current in both Case ,I
Using Ohm's Law
• V = IR
Where,
V is the Voltage
I is the Current
R is the resistance.
For Bulb
V = IR
Substitute the value we get
➺ 220 = I × 1200
➺ I =
→ I = 0.18 A
Therefore, the current flow in the bulb is 0.18 Ampere.
For Electric Heater
V = IR
➺ I =
Substitute the value we get
➺ I =
➺ I = 2.2 A
Therefore, the current flow in the bulb is 2.2 Ampere.

Answer:
[ Question 1 ]
Given :
- Voltage= 220V.
- Resistance = 1200Ω.
To Find :
- How much current will an electric bulb
Solution :
Concept :
- Ohm's law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).
follow !me
Current (I) = Voltage (V)/ Resistance (R).
Substitute all values :
I = 220V/1200Ω.
I = 11/60
I = 0.183 A.
Hence 0.183 A. current will an electric

[ Question 2 ]
Given :
- Voltage= 220V.
- Resistance= 100Ω.
To Find :
- how much current will an electric heater call grow
Solution :
I = V/R.
Substitute all values :
I = 220V/100Ω.
I = 22/10
I = 2.2 A.
Hence 2.2 A. current will an electric heater call grow
more to know :
Current:
- Electric current is expressed by amount of charge flowing through a cross section of a conductor in unit time.
Voltage :
- Voltage also called the Potential difference is the measure of difference in charges at the two positive and negative ends of any cell or appliance.
Resistance :
- Resistance in a conductor can be defined as the opposition offered to the flow of electrons.
