Two lamps, one rated \(100\ W\) at \(220\ V\), and the other \(60\ W\) at \(220\ V\), are connected in parallel to electric mains supply. What current is drawn from the line if the supply voltage is \(220\ V\)?
[Note: Enter the answer up to three decimal places.]
The formula for power is
\(\)
From the above formula, the value of current can be easily calculated.
Case 1:
Power, \(P\) \(=\) \(100\ W\)
Voltage, \(V\) \(=\) \(220\ V\)
Current \(=\) \(A\)
Case 2:
Power, \(P\) \(=\) \(60\ W\)
Voltage, \(V\) \(=\) \(220\ V\)
Current \(=\) \(A\)
The current drawn from the line is .
