Answer 1

Answer:

if connected in series the overall resistances increases which leads to decrease in current flow making the heat producing more cause the current has to keep working to keep itself glowing causing the heating effect of current and visa versa for the parallel connections

Answer 2

Case I: 9.17 Amperes

Case II: 4.58 Amperes

Case III: 18.33 Amperes

Step-by-step explanation:

Given:

Voltage(V) = 220 Volts

Resistance of Coil A, Ra = 24 ohm

Resistance of Coil B, Rb = 24 ohm

Case I: When coils are used separately.

Applying the formula,

We get,

Therefore, the current flowing in this circuit is 9.17 Amperes.

Case II: When coils are used in series.

Equivalent Resistance,

R = 24 + 24 = 48 ohms

Applying Formula V = IR,

Therefore the current flowing is 4.58 Amperes.

Case III: When coils are used in parallel.

Equivalent Resistance,

Current Flowing,
