The joule is a unit of energy.
ForV andmA, the power is
A given power supply is capable of providing 6 A for 3.5 h. Its ampere-hour rating is
The watt is the unit of power.
Power rating is related to resistance value.
The power rating of a carbon-composition resistor that is to handle up to 1.2 W should be
A resistor normally opens when it burns out.
The power rating of a resistor determines the minimum power that it can handle safely.
At the end of aday period, your utility bill shows that you have usedkWh. What is your average daily power?
When the pointer of an analog ohmmeter reads close to zero, the resistor being measured is
InkW, there are
How much continuous current can be drawn from aAh battery forh?
Energy equals power multiplied by time.
A battery is one type of power supply that converts chemical energy into electrical energy.
A 3.3 k resistor dissipates 0.W. The current is
The capacity of a battery is measured in milliamperes.
Energy is equal to power multiplied by voltage.
A half-watt is equal to how many milliwatts?
In 0.W, there are
If you usedW of power forh, you have used
Three hundred joules of energy are consumed ins. The power is
A certain appliance usesW. If it is allowed to run continuously fordays, how many kilowatt-hours of energy does it consume?
If it takesms to use 12,J of energy, the power is
A resistor is connected across the terminals of a 3 V battery. The power dissipation of the resistor is
