1. a circuit with a 6 v battery is connected to a light bulb that has a resistance of .5 ohms. how much current is flowing through the light bulb when it is turned on?

2. a car has a 12 v battery. when someone starts the car 200 amps of current move through the cars starter. what is the resistance of the cars starter?

3. a toy electric car uses 2 amps of current when the car is running. if the resistance of the car's motor is 3 ohms, what is the voltage of the battery in the car?

I = 12 ampere

R = 0.06 ohm

V = 6 Volt

Explanation:

1)

Given that,

voltage of battery that is connected to a light bulb = 6v

resistance in the circuit = 0.5 ohms

current Is flowing through the light bulb

I = V / R

I = 6/0.5

I = 12 ampere

2)

Given that,

voltage of car battery = 12v

amount of current that moves through the car starter = 200amps

resistance of the cars starter

R = V / I

R = 12 / 200

R = 0.06 ohm

3)

Given that,

current used by the toy electric car = 2 amps

resistance of the car's motor = 3 ohms

voltage of the battery in the car

V = I R

V = 2(3)

V = 6 Volt

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
