Class X On which of the following no “plus” or “minus” sign is marked a battery an ammeter a voltameter a resistor The electric power is the product of __________ and the __________. potential difference, current work done, 1J(1 Joule) Ohm-meter (Ωm) watt (W A galvanometer is used to measure potential difference detect direction of current measure amount of current flowing measure electric power of the circuit The resistance of a conductor is directly proportional to its _____. 18 Ω Ohm-meter (Ωm) work done, 1J(1 Joule) length : Two charged bodies having equal potential are connected through a conducting wire, in this case current will flow current will not flow cannot say current will flow if a resistor is also connected Do you really want to submit this quiz?
