An E. M.F. Of 75 volts is placed across a 15 ohm fixed resistor. What current flows through the resistor?

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

What are the similarities & differences between a thermistor and a light dependent resistor in physics?

The diagram shows a wave. the quantity shown is the amplitude. this quantity is directly proportional to which of these other quantities? a) energy b) frequency c) period d) wavelength
