What battery voltage would you need to send 2.5 A of current through a light bulb with 3.6 Q of resistance? * 1.2 1.5 12 9.

3.0 A of electric current pass through a 4.0 Ω resistor. How many electrons pass through the resistor in 5 minutes?

A certain person will experience a mild electric shock when the current between two fingers exceeds 72uA. If. The resistance between their thumb and index finger is measured to be 215ohms, how much voltage can be applied before they feel a mild shock? a. 15.5uV b. 33.5uV c. 29.9uV d. 29.9V e.15.5V

A 36 V battery is connected to a network of resistors with R1 = 45 Ω, R2 = 36 Ω, and R3 = 108 Ω. What is the potential difference across R3? (in V) (a) 54.0 V (b) 13.5 V(c) 27.0 V(d) 36.0 V

Your car battery is dead, and your friends are helping you start your car with cheap jumper cables. One cable carries current from their car to your car, and a second cable returns that current to their car. As you try to start your car, a current of 80.0 A flows through the cables to your car and back, and a voltage drop of 6.00 V appears across each cable. If you replace the cheap cables with cables having half their electric resistance, what voltage drop will appear across each new cable if the current doesn't change? AV= i

a) From the graph, determine the emf (ϵϵ) of the battery. b) From the graph, determine the internal resistance (r) of the battery.

Giant electric eels can deliver a voltage shock of 5.00×102 V and up to 1.00 A of current for a brief time. What is the maximum power a giant electric eel can deliver to its prey during this time? maximum power:   W The body of a snorkeler swimming in salt water has a resistance of about 605 Ω. If the snorkeler is unfortunate enough to be struck by the eel, what current will flow through her body? current:     A A current of about 500 mA can cause heart fibrillation and death if it lasts too long. Is the current through the swimmer in this case large enough to be dangerous? yes no What power does the snorkeler receive from the eel? power:
