Question

hello, sir/ madam i have some questions:
1)If the peak value of A.C voltage is volts, then its roots means square value will be?
2)Suppose an electron is chasing a proton up this page when suddenly a magnetic field directed perpendicular into the paper is turned on. What happens to the particles?
3)An inductor draws 30 ampere when connected across the terminals of generator A and 6 ampere when connected to B. Assuming the same impressed voltage can you tell which of the two generators A or B is an A.C machine? Give reason

4)When we move in an electric field, the potential changes at the rate of 10 Vm-1. What is the electric intensity?

Explanation / Answer

1) root mean square value is also in volts 2) Both the particles will trace the circular tracks in opposite directions. 3) B is A.C machine as for D.C there will be no inductive reactance offered by the inducor hence the current will be maximum . For AC the inductive reactance depends on frequency and due to induced emf the value of the current is minimum. 4) Electric intensity is the change in potential with distance . Hence E = 10 V/m
