Two 12 volt batteries connected in parallel will give you: a) A total of 12 voltsb) A total of 24 voltsc) A total of 6 voltsd) None of the above33. In a 24 volt system with a total resistance of 12 ohms, the current in the system is: a) 1/2 ampsb) 24 ampsc) 2 ampsd) None of the above34. A parallel circuit has: a) Only one pathb) Only two pathsc) Two or more pathsd) None of the above35. TRUE/FALSE: A voltmeter is usually connected in parallel in a circuit.36. TRUE/FALSE: Adding a resistor to a series circuit increases current flow.37. TRUE/FALSE: You should have power in the circuit or component when checking for continuity.38. TRUE/FALSE: A battery is made of many cells in parallel.39. TRUE/FALSE: A voltmeter could be damaged when connected in series with current flowing.40. TRUE/FALSE: When a circuit is connected so that current flow is divided when passing through the units, it is called a "series" circuit.41. TRUE/FALSE: When resistances are connected in parallel, the total resistance is less than the value of the smallest resistance.42. TRUE/FALSE: If an "open" occurs in a series circuit, no current will flow in any other part of the circuit.43. TRUE/FALSE: An ammeter indicates the current flowing through the circuit in which it is connected.44. TRUE/FALSE: Voltage drop is the difference in electrical pressure between any two points in a circuit.45. TRUE/FALSE: The current flow varies at different points in a series circuit.46.
