    Well, that's correct too but why go for such a rough value? Underroot 2, underroot 3, pi -2, all are correct.

    Advice For Physics

    DC Motor is used to induce a force using current and magnetic field. The force direction can be found out by Fleming's Left Hand Rule. The split-ring commutator ensures that the coil keeps rotating in the same direction (by reversing the current every half turn). The magnitude of force can be...

    Advice For Physics

    Transistors are like electric switches, they only work if the voltage across them is high enough and the direction of current is correct. You don't have to do them, they are optional.

    Advice For Physics

    Well, you asked for the function. Other than all this, you need to no that; There are four types of resistors: -Fixed. -Variable. -Thermistor. -Light Dependant. You also need to know that the diode only works when connected correctly in the circuit, that is positive (+ve) to the base of the...

    Advice For Physics

    A resistor is used to control the current flowing in a circuit. A rectifying diode is used to smoothen a.c. currents so that they have rectified curve (almost like d.c.). A light emitting diode (LED) is lit when it is connected in a circuit correctly.
