Circuit is closed. Current is flowing.
What's happening? The moving yellow dots represent electrical current flowing around the closed circuit.

Ohm's Law: I = V / R
Current equals voltage divided by resistance.

Electrical Power: P = V × I
Increase the voltage while keeping resistance constant, and the current increases.
Increase the resistance while keeping voltage constant, and the current decreases.

Opening the switch breaks the circuit, so the current and electrical power become zero.

DARLINGTON TRANSISTOR

-
  A Darlington transistor circuit is a combination of two bipolar transistors connected in such a way as to provide a high current gain. Advantages: High current gain High input impedance High voltage amplification Drawbacks: High voltage drop High power dissipation High thermal resistance Applications: Power amplification Motor control High voltage switching Challenges: Heat dissipation Stability of the circuit Numerical: High current gain: typically 1000 or more Formula: Common emitter current gain (beta) of Darlington transistor circuit = β1 * β2, where β1 and β2 are the current gains of the individual transistors. Derivation: Darlington transistor circuit is derived from the basic bipolar transistor configuration. Frequency range: The frequency range of Darlington transistor circuit depends on the individual transistors used and can range from a few Hz to several MHz. Year of discovery: Darlington transistor was invented by Sidney Darlington in 1953. Waveform: The waveform of D...
