Of the following, the copper conductor that has the least resistance is a. thin, long, and hot b. thick, short, and cool c. thick, long, and hot d. thin, short, and cool 6. If all the components of a circuit are connected in series, the physical quantity that is the same at all points is the a. voltage b. current c. resistance d. power 7. The ratio of the potential difference across a conductor and the current in the conductor is called the of the conductor. a. electrical potential b. conductance c. capacitance d. resistance 8. Two lamps, one with a thick filament and one with a thin filament of the same length and material, are connected in series to a battery. The voltage is greater across the lamp with the a. thick filament b. thin filament c. voltage is the same for both 9. Which statement is correct? a. Charge flows in a circuit. b. Voltage flows through a circuit. c. Resistance is established across a circuit. d. Current causes voltage.

Solution

here,

5)

resistance = resistivity * length /area

so,

the copper conductor has least resistance is b.short ,thick and cool

6)

b.) current is same in the series circuit

7)

the ratio of potential difference and the current in the conductor is called d.) resistance

R = V/I

8)

the thin filament has more resistance ,

so the voltage is greater as , V = I * R

so , the voltage is greater along b.)thin filament
