I need help with these question from physics. I decided to take on an extra practice worksheet to study but I'm stuck. Please solve and explain the questions below. Everything is given in the attachments, thanks!!
Which of the following statements are true about electric current? * 4 points SELECT TRUE or FALSE TRUE FALSE Electric current is greater if more charges are moving 0 0 through the wire The electric current in a circuit will increase as the O 0 battery voltage is increased A light bulb with a greater resistance will have a greater 0 0 current. Thinner wires carry smaller 0 O currents Which of the following statements are true about electric resistance? * 4 points SELECT TRUE or FALSE TRUE FALSE Resistance in circuit will increase if the wire carrying O O is shortened. Resistance can be found by dividing voltage by current. 0 O A 5-Ohm resistor would allow a current of 0.5 A if a 2.5 V battery was hooked up to the O O circuit. When a circuit is first turned on, there is less resistance 0 0 because the wire is still cool. Which of the following statements are true about a series circuit? SELECT TRUE or FALSE Series circuits are rarely used in households The equivalent resistance of a circuit decreases as more and more resistors are placed in series in the circuit. Suppose that three identical resistors, each with a resistance of 6 Ohms, are placed in series with a 36 V Battery. The total current in the circuit is 2 A. Suppose that two identical resistors are placed in series with a 24 V battery. The total current in the circuit is 3 A. The resistance of each resistor is 4 Ohms. TRUE FALSE Which of the following statements are true about a parallel circuit? SELECT TRUE or FALSE The total current in a circuit increases as more resistors are placed in parallel because this reduces the total resistance of the circuit. Suppose that three identical resistors of 3 Ohms are placed in parallel with a 12 V battery. The voltage across each resistor is 12 V. For a parallel section, voltage is split between the branches and current is the same for both branches Outlets are wired in parallel. Plugging more household items into the same outlet will reduce the amount of voltage each item receives. TRUE FALSE * 4 points * 4 pointsStep by Step Solution
