A hot plate of an electric over connected to 220 voltmeter line has two resistance coil A aand B each of 24hom resistance which may be used separately in series or in parallel what are
Answers
Answer:
Supply voltage, V= 220 V
Resistance of one coil, R= 24Ω
(i) Coils are used separately
According to Ohm’s law, V= I1R1
Where I1 is the current flowing through the coil
I1 = V/R1 = 220/24 = 9.166 A,
Therefore, 9.16 A current will flow through the coil when used separately.
(ii) Coils are connected in series
Total resistance, R2 = 24 Ω+ 24 Ω= 48 Ω
According to Ohm’s law,
V = I2R2
Where I2 is the current flowing through the series circuit
I2 = V/R2 = 220/48 = 4.58 A,
Therefore, 4.58 A current will flow through the circuit when the coils are connected in series.
(iii) Coils are connected in parallel
Total resistance, R3 is given as
According to Ohm’s law,
V= I3R3
Where I3 is the current flowing through the circuit
I3 = V/R3 = 220/12 = 18.33 A,
Therefore, 18.33 A current will flow through the circuit when coils are connected in parallel.
