How would you classify a resistor and a capacitor?
A capacitor regulates the amount of current flowing in an electronic circuit while a resistor is an electrical component that stores energy in the form of electric charge.
A resistor regulates the amount of current flowing in an electronic circuit while a capacitor is an electrical component that stores energy in the form of electric charge.
A capacitor is a device that stores chemical energy and converts it to electrical energy while a resistor is a small device that allows an electric current to flow through in one direction.
A resistor is a device that stores chemical energy and converts it to electrical energy while a capacitor is a small device that allows an electric current to flow through in one direction.
If you are going to arrange the steps for measuring the voltage of a battery, how would it be?
2. Take the reading on the multimeter. If the reading shows a value greater than 7V for a 9V battery, the battery is still fit to use.
3. Connect the multimeter leads to the battery's terminals.
5. Rotate the knob of the multimeter and set it to 15-20V DC voltage
4. Connect the plug of the red probe to the VΩmA port of the multimeter, and the black probe to the COM port.
1. If the reading shows a considerably low value (say <1V for a 9V battery), the battery may be faulty or dead and needs to be replaced.
In storing the multimeter for a prolonged period of time, what could be done to minimize the destruction of the multimeter?
