If the polarity of the battery had been switched in the experiment. (a) the volt

Question

If the polarity of the battery had been switched in the experiment. (a) the voltage would read backward. (b) the ammeter would read backward. (c) the magnitude of the current and the voltage would be the same. (d) of the above According to Ohm's law, if the resistance of a circuit is doubled without changing the voltage, the current will (a) be doubled, (b) remain unchanged, (c) be cut in half, (d) be reduced to aero In a series resistance circuit, (a) the voltage drop across each resistance is the same, (b) the current through each resistance is the same, (c) the equivalent resistance is less than the smallest resistance, (d) the current divides between the resistance In a parallel resistance circuit, (a) the voltage drop is the same across resistance, (b) the t is always the same through each resistance, (c) the equivalent resistance is equal to the sum of the resistances, (d) the current does not depend on the resistances For a series parallel circuit, the equivalent resistance is greater than for (a) the resistance connected in series, (b) the resistances connected in parallel, (c) an open circuit, An equivalent unit to the second is (a) V/F, (b) F/Ohm, (c) F middot Ohm, (d) V-Ohm

Explanation / Answer

10. (d) all of the above

11. (c) be cut in half

   because I = V/R

12.(b) the current through each resistance is same

13.(a) the voltage drop is the same across each resistance

14. (b) the resistance connected in parallel
