Current 2 of 9 To measure the force in Question 6, we would use a: Ammeter 3 of 9 A voltmeter should be placed: At either end of the circuit appliance 4 of 9 Ohm's Law states that the current is proportional to the voltage, keeping a fixed resistance. However, this is not true for: Metals 5 of 9 The turning effect of a current-carrying coil in a magnetic field induces a current. This is how ___ generators work. AC 6 of 9 To increase the size of an induced current, we can NOT: Increase the temperature 7 of 9 A transformer increases a current from 50amps to 150amps. This transformer could be considered a: Step up transformer 8 of 9 If two appliances in a parallel circuit have resistances of 5 & 9, calculate the total resistance. 3.214 9 of 9
