Electric current is the flow of electric charge and is measured with an ammeter. The SI unit for measuring electric current is the ampere (A), which is equal to a flow of one coulomb of charge per second. While there are several methods of measuring current, the most common method is ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
(just a sensitive ammeter) needle move as i do this in the gif below. the greater the current, the greater the voltage. you don't see it in my demonstration, but the angle between the magnetic field and the coil of wire is important. this means that instead of moving the magnet, ...
Students often get confused when connecting an ammeter to a breadboard circuit. How can the meter be connected so as to intercept all the circuit’s current and not create a short circuit? One easy method that guarantees success is this: ...

is measured by leakage current. Knowing the leakage current and applied voltage, the insulation resistance can be calculated based on the ohm’s law. There are two basic ways to measure the leakage current. First, apply an ammeter in series with the capacitor and voltage source (see Figure 1...
Install the inline ammeter into the DC circuit by placing the meter in series with one of the electrical circuit wires. Again this meter can be placed on either the positive (+) wire or the negative (-) wire of the direct current circuit. All power though must pass through the inline se...
The remaining resistors, capacitor, and milliammeter can be junk box items. The diode is non-critical, a 1N914 / 1N4148 type should be fine. A 1N34 would be better in theory, but most any small signal diode should work. 1N914 datasheet If you want to use this with higher power, ...
Then turn the control to the ON position. If the unit works, the problem is probably a misaligned lock unit. Adjust the lock unit with a screwdriver. If this doesn't solve the problem, the switch may be faulty. Step 2: Test the switch with a volt-ohm-milliammeter (VOM) set to the...
