**Heat A Copper Wire, Its Electric Resistance** - Nine sixty five. The diagram below suggests a circuit with resistors. Sixty eight. A 6.Zero-ohm lamp calls for 0.25 ampere of cutting-edge to function. Wherein circuit underneath would the lamp function efficiently whilst transfer s is closed? What is the reading on ammeter a? 1.3 a three.Zero a 1.Five a zero.Seventy five a sixty six. The diagram underneath represents an electric powered circuit such as a 12-volt battery, a three.Zero-ohm resistor, r 1, and a variable resistor, r 2. At what fee need to the variable resistor be set to supply a current of 1.Zero ampere through r 1? 6.0 þ 3.0 þ nine.0 þ 12 þ 67. In the circuit represented through the diagram beneath, what is the studying of voltmeter v? V 30. V 2.0 v forty. V inside the circuit diagram above, what's the capacity distinction across the three.0-ohm resistor? 1.Zero v three.0 v 2.Zero v 1.Five v.

7 fifty one. The diagram underneath represents a series circuit containing 3 resistors. 54. A nine.0-volt battery is attached to a four.Zero-ohm resistor and a 5.0-ohm resistor as shown in the diagram beneath. What's the present day via resistor r 2? 1.Zero a 3.Zero a 0.33 a nine.Zero a 52. The diagram below represents a easy electric powered circuit. What is the present day in the five.Zero-ohm resistor? 1.Zero a 1.8 a 2.3 a four.0 a fifty five. The diagram below represents an electric powered circuit. How an awful lot charge passes thru the resistor in 2.0 seconds? 6.Zero c 8.Zero c 2.Zero c 4.Zero c fifty three. A 30.-Ohm resistor and a 60.-Ohm resistor are linked in an electric circuit as shown underneath. If the voltage among a and b is 10 volts, the voltage among b and c is five v 15 v 10 v 20 v 56. Three resistors of 20. Ohms, 30. Ohms, and 60. Ohms, respectively, are linked in series with a battery. A modern-day of 2.Zero amperes will flow thru this circuit while the capability difference of the battery is 10. V 110 v 20. V 220 v 57. As greater resistors are brought in series throughout a battery, the capability drop throughout each resistor decreases stays the equal increases in comparison to the electric cutting-edge via the 30.-Ohm resistor, the electric contemporary thru the 60.-Ohm resistor is smaller the identical larger.
