4) A resistor is added to a circuit that already has one resistor carrying current from a battery. If adding the resistor to the circuit causes the current owing from the battery to increase, was the resistor added in series or in parallel? a added in series b added in parallel St A resistor is added to a circuit that already has one resistor carrying current rom a battery. If adding the resistor to the Circuit causes the current owing from the battery to decrease, was the resistor added in series or in parallel? a added in series b added in parallel 6) Hyou have a circuit with a battery with voltage V sending current [through a resistor R, what quantity will you calculate it you multiply the voltage by the current? a resistance b power You can calculate the same quantity by using Ohm's Law to substitute for V or I m create atemate versions of this equation. Put an \"X\" by each equation that will give the sarue result as above. a V1 F b R3 T c 12.? :1 R12 Note: you can test your choices by piclolng a value of each variable and substituting into eac equation. Avoid using 1 as a quantity. 7) When a smoke detector is sounding the alarm, a 9 Volt battery is sending an average of 0.5 A of current to the alarm speakers. What is the power usage? Show how you get your answer. 8) The average household consumes electrical energr at a rate of 1250 W. Calculate how much emery this is in 1 average day (24 hr) in kWh units. 9) A fuse is one device that can prevent electrical res by shutting off the power when too much current is owing through the wiring. A more common device today that does the same thing is a a transformer b diode c circuit breaker d transistor See chapter 7 section 5 for help on this question. 10] In which device is ohmic heating not desirable? \f
