Explanation When the motor is plugged, the act as closed and the inductor act as a short circuited as shown in the figure below. Figure-(1) Write the expression based on junction rule. ∑ junction I = 0 Here, ∑ junction I is the sum current at the junction. Write the expression to obtain the loop rule. ∑ closed loop Δ V = 0 Here, ∑ closed loop Δ V is the potential drop across each element in a closed circuit. Write the expression to obtain the voltage across the loop a e f b a . 12.0 V − ( 7.50 Ω ) I − 10.0 V = 0 Here, I is the current flowing in the circuit. Further solve the above equation. I = ( ( 12.0 − 10.0 ) V 7.50 Ω ) = 2.00 V 7.50 Ω = 0

Magnetic Field Of Coaxial Cable

The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequen…
