How much current is in a circuit that includes a 9-volt battery and a bulb with a resistance of 12 ohms?

Current = (voltage) / (Resistance)

If those are the ONLY things in the circuit, then

Current = (9 volts) / (12 ohms)

Current = 0.75 Ampere

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
