Question

TWO unequal resistors are in series in a circuit. The one with the most power is a) the smaller R b) the larger R c) the first one d) the second one Two unequal resistors are in parallel in a circuit. The one with the most current is a) the one with the larger voltage b) the smaller R c) the larger R d) they have the same current When the frequency of an AC circuit increases, the power a) increases b) decreases c) remains the same d) not enough information to answer the question Kirchhoff s first law (the point law) is based on conservation of a) energy b) momentum c) charge d) parity The north pole of a magnet falls toward a horizontal coil. Viewed from above the induced current flows in the coil a) east b) clockwise c) counterclockwise d) up

Explanation / Answer

power

P = V^2/R

when R is small P is large

the one with most power is smaller R

option (a) is correct answer

(6)

from the Ohm's law the one with most current is the smaller R

option(b) is correct answer

(7)

P= VI cos phi

here phi is phase angle

phase angle depens on the frequency so frequency increase power also increases

(8)

conservation charge

(9)

by the Lenzs law the direction of induced current will be counter clock wise
