Answer -
each of 24 Ω resistance, which may be used separately, in series, or in parallel. What are the currents in the three cases?
Answer
Case (i) When coils are used separately
Using Ohm’s law, we can find the current flowing through each coil as follows:
9.166 A of current flows through each resistor when they are used separately.
Case (ii) When coils connected in series
The total resistance in the series circuit is 24 Ω + 24 Ω = 48 Ω
The current flowing through the series circuit is calculated as follows:
Therefore, a current of 4.58 A flows through the series circuit.
Case (iii) When coils connected in parallel
When the coils are connected in parallel, the equivalent resistance is calculated as follows:
The current in the parallel circuit is 18.33 A.
