6 FAQs about [Does the switch transmit power and store energy ]
Does switching consume power?
Of course there is also the energy needed to "throw" the switch, in the form of gate charge/discharge. Switching results in current such that a voltage changes. Resistance is never zero, so until we have superconducting ICs, switching always consumes power (= I^2*R).
What is an electric switch?
An electric switch is a device that interrupts the electron flow in a circuit. Switches are primarily binary devices: either fully on or off and light switches have a simple design. When the switch is turned off, the circuit breaks and the power flow is interrupted. Circuits consist of a source of power and load.
What happens when a switch is turned off?
When the switch is turned off, the circuit breaks and the power flow is interrupted. Circuits consist of a source of power and load. How do you solve circuit problems in physics? What does a switch do in a circuit physics? How do you calculate current when a switch is open? How do you solve a series and parallel circuit problem?
What causes energy dissipation if a switch is turned off?
When you turn them off, they simply stop to consume energy. So continuous switching is not a major cause of energy dissipation in this case (but there are other losses anyway). BUT for switching applications (logic circuits and power circuits), MOSFETs are used instead of transistors. A mosfet consumes very little energy in its gate.
Does switching cause power dissipation?
Power is energy per second. Switching therefore causes power dissipation. If you do this switching at a low frequency the power is lower; if you do it at a high frequency, the power is higher. Consider a MOSFET switching. Switching is a transient event, so losses are not usually modeled as "power". Each switching action dissipates a bit of energy.
What happens if a switch is repeated cyclically?
So, if this is repeated cyclically, you are taking energy from the power rails cyclically and converting that energy to heat. Power is energy per second. Switching therefore causes power dissipation. If you do this switching at a low frequency the power is lower; if you do it at a high frequency, the power is higher. Consider a MOSFET switching.
