1. (a) The equivalent resistance of a group of resistors connected in parallel is
(i) Greater than any of the resistors in the group,
(ii) Less than any of the resistors in the group, or
(iii) Neither of the above.
(b) The equivalent resistance of a group of resistors connected in series is
(i) Greater than any of the resistors in the group,
(ii) Less than any of the resistors in the group, or
(iii) Neither of the above. Justify your answers by considering a circuit consisting of a 3.0-Ω resistor and a 5.0-Ω resistor connected across a 12-V battery.
2. Would a fuse or circuit breaker work successfully if it were placed in parallel with the device it was supposed to protect?
