Question

A 10-ohm resistor lias a constant current. If 1200 C of charge flow through it in 4 minutes what is the value of the current? Five 10-Ohm resistors are connected in series and the combination is connected to a 15-V emf device. The current in any one of the resistors is: An electron moves in the negative x direction, through a uniform magnetic field that is in the negative y direction. The magnetic force direction on the electron is: In Ampere's law. the integration must be over a Faraday's law states that an induced emf is proportional to the rate of change of the

Explanation / Answer

6.) Resistance= 10 ohm

charge flowed = 1200 C

Time taken= 4 minute = 4*60 =240 seconds

Value of current = rate of change of charge with respect to time

=1200/240 = 5 Ampere

7.) five 10 ohm resister in series

so Equivalent resistance of all = 10*5=50 ohm

15 volt emf device

so current = 15/50 = 0.3 Ampere

8.) the direction of force on electron will be in negative Z direction.

9.)closed surface.

10.) The induced electromotive force(emf) in any closed circuit is equal to the negative of the time rate of change of the magnetic fluxenclosed by the circuit.
