(II) What is the internal resistance of a 12.0-V car battery whose terminal voltage drops to 8.8 V when the starter motor draws 95 A? What is the resistance of the starter?
Please draw detailed pictures!!! 3. (II) What is the internal resistance of a 12.0-V car battery whose terminal voltage drops to 8.8 V when the starter motor draws 95 A? What is the resistance of the starter?
An automobile starter motor is connected to a 12.0 V battery. When the starter is activated it draws 150 A of current, and the batten, ' voltage drops to 7.0 V. What is the battery's internal resistance?
6) Car batteries supply a "nominal 12V voltage, but due to the internal resistance of the battery the actual voltage can be somewhat smaller. Consider this situation: Cars have an electric starter motor that draws 90A of current to turn over the engine pistons and start the car. While this 90A current is being drawn from the battery, the terminal voltage across the battery drops down to 11V. Use this information to find the internal resistance of the battery.
A car battery has an emf of 12.0 V and an internal resistance of 0.20 Ω. While the car is running, the resistance of the rest of the car (the “load” resistance) is 1.00 Ω. What is the current through the battery? What is the terminal voltage of the battery? What is the power delivered to the rest of the car? What is the power dissipated as heat by the internal resistance of the battery?
The starter motor of a car engine draws a current of 180A from the battery. The copper wire to the motor is 4.20mm in diameter and 1.2 m long. The starter motor runs for 0.830s until the car engine starts. A) How much charge passes through the starter motor? B) How far does an electron travel along the wire while the starter motor is on? Q2:What is the resistance of A) A 1.90 m long copper wire that is 0.100mm...
(a) A car battery with 12 V emf and internal resistance 0.05 is supplying a current of 50 A to the starter motor. Calculate the terminal voltage across its terminals of the motor? At what rate energy is dissipated in the battery? (3 marks) (b) Alisha is afraid of darkness and so sleeps with a 7.5W night light bulb on. She turns it on before getting in bed and tums it off 8 hours later. Determine the annual (365 days)...
The starter motor of a car engine draws a current of 140 A from the battery. The copper wire to the motor is 4.90 mm in diameter and 1.2 m long. The starter motor runs for 0.800 suntil the car engine starts. a) How much charge passes through the starter motor? b) How far does an electron travel along the wire while the starter motor is on?
PLEAASEE HELP!! A battery with an emf of 12.0 V shows a terminal voltage of 11.6 V when operating in a circuit with two lightbulbs, each rated at 4.0 W (at 12.0 V),which are connected in parallel. What is the battery's internal resistance?
1. A 12-V car battery has an internal resistance of 0.020 Ω. When the headlights and stereo are on, a current of 25.0 A is drawn from the battery. What is the value of the terminal voltage when this current is drawn from the battery? 12 V, 9.0 V, 12.5 V, or 11.5 V 2. A car battery seems to be malfunctioning (not providing the proper voltage and current to start your car). While the car is off and you...
