The main power producers in an electrical system are the battery and alternator. The alternator puts 14 volts of alternating current into the electrical system and resistors. The resistors only allow a fraction of the AC voltage produced to reach the systems' sensitive components

A 4700ohms resistor rated as 5watts find out it maximum safe working current?
Power dissipated = I2 RI = sqrt( P/R ) = sqrt(5/4,700) = 32.6 mA . (rounded)Note:It's only "safe" if the power actually dissipates, i.e. doesn't just hang around the resistor.32.6 mA is 'safe' if the resistor is heat-sinked, or at least out in the open air. It's not safeif the resistor is wrapped in a cozy blanket.
What is the function of a cement resistor?
A cement resistor is typically used as a power resistor (a resistor whose power rating is greater than 1 W).
Voltmeter is connected in parallel with resistor?
A voltmeter can be connected in parallel with a resistor to show the voltage across the resistor.
What is series dropping resistor?
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
What do the first 3 bands on a resistor indicate?
