A 220 volt and 800 watt electric kettle and three 220 volt and 100 wat...
Given:
- Electric kettle: 220V, 800W
- Bulbs: 220V, 100W (3 bulbs)
- Electric supply: 220V
To Find:
Total current when the combination is connected in parallel.
Solution:
First, let's calculate the current flowing through the electric kettle and each bulb.
Calculating Current for Electric Kettle:
Using Ohm's Law: P = VI, where P is power, V is voltage, and I is current.
800W = 220V * I
I = 800W / 220V
I ≈ 3.64A
Calculating Current for Bulbs:
Using Ohm's Law: P = VI, where P is power, V is voltage, and I is current.
For each bulb:
100W = 220V * I
I = 100W / 220V
I ≈ 0.45A
Calculating Total Current:
In a parallel circuit, the total current is the sum of the individual currents.
Total current = Current for electric kettle + Current for bulbs
Total current = 3.64A + (0.45A * 3)
Total current ≈ 3.64A + 1.35A
Total current ≈ 4.99A
The total current when the combination is connected in parallel with a 220V electric supply is approximately 5.0 amperes, which is the correct answer (option B).
- Electric kettle: 220V, 800W
- Bulbs: 220V, 100W (3 bulbs)
- Electric supply: 220V
To Find:
Total current when the combination is connected in parallel.
Solution:
First, let's calculate the current flowing through the electric kettle and each bulb.
Calculating Current for Electric Kettle:
Using Ohm's Law: P = VI, where P is power, V is voltage, and I is current.
800W = 220V * I
I = 800W / 220V
I ≈ 3.64A
Calculating Current for Bulbs:
Using Ohm's Law: P = VI, where P is power, V is voltage, and I is current.
For each bulb:
100W = 220V * I
I = 100W / 220V
I ≈ 0.45A
Calculating Total Current:
In a parallel circuit, the total current is the sum of the individual currents.
Total current = Current for electric kettle + Current for bulbs
Total current = 3.64A + (0.45A * 3)
Total current ≈ 3.64A + 1.35A
Total current ≈ 4.99A
The total current when the combination is connected in parallel with a 220V electric supply is approximately 5.0 amperes, which is the correct answer (option B).
