. Draw a simple circuit in which two cells of emf 1.5 volts connected in series. Two resistors 5Ω and 10Ω are connected in parallel, plug key, ammeter are connected in series. Voltmeter is connected across the 10Ω resistor.

An electric current is flowing through the cord below.what will happen to this current if a magnet is brought near the cord? a. the electric current will stop flowing. b. it will exert a force on the voltage. c. the resistance of the wire will decrease. d. it will exert a force on the electric current.

Electromagnetic induction. a coil of wire contains n turns and has an electrical resistance r. the radius of each turn is a. initially, inside the coil there exists a uniform magnetic field of magnitude b0 parallel to the axis of the coil. the magnetic field is then reduced slowly. the current induced in the coil is i. how long does it take for the magnitude of the uniform field to drop to zero?

Which of the following are appropriate acceleration units?
