If a 200 mA power supply is used on a circuit needing 2 amp it would overload the power supply. Two amps equates to 2000 milliamps. Trying to pull 2000 milliamps from a device that is only capable of supplying 200 milliamps is not advisable. The excessive current draw would most likely burn the wires open and render the power supply useless.

What happens if a 2 amp power supply is used on a circuit needing 200 mA?

Everything would work as designed if you used a 2 amp power supply for a 200 ma circuit.It's important to not go OVER the designed capacity of the power supply, and in fact, it's a good idea to make sure the power supply has at least double the capacity of the load current.


What happens if there is a break in a serious circuit?

A break in an electrical circuit will cause the circuit's load to stop operating.


Is a 24VDC power supply short-circuit protected?

That would depend on the power supply.

Why is a power supply even after the power supply has been disconnected?

because the power still are in circuit of the motherboard and you have to drain the system


How is a series circuit and a parallel circuit alike?

Both take current and energy from the power supply and dissipate power.


What is the flow of an electrical current in a circuit outside the power source?

Usually a circuit is connected to a power source, which could be a battery or an outlet. When this happens current flows through the circuit. The power supply raises electrical charges through the required potential difference, and then in the circuit the charges flow down the potential gradient giving up their energy.


What should a complete circuit have a minimum of?

a power supply (eg: battery) and a load (eg: resistor) even a piece wire shorting two terminals of the power supply is a closed circuit


What is the condition of maximium power transfer of circuit?

Maximum power transfer happens in a circuit when the resistance of the circuit equals the reactance. Impedance Z = R + jX. At R=X, maximum power transfer happens.


What happens in a circuit if you increase the voltage of the battery driving it?

The power in the circuit will increase.


What is the power of a ciruit with 10 ohmns 10 volts and 2 amps?

Well, first of all, if the resistance of the circuit is 10 ohms and you connect 10 volts to it,then the current is 1 Amp, not 2 . So either there's something else in your circuit thatyou're not telling us about, or else the circuit simply doesn't exist.-- If you connect some voltage to some resistance, then the resistance heats up anddissipates (voltage)2/resistancewatts of power, and the power supply has to supply it.-- If there is some current flowing through some resistance, then the resistance heats up anddissipates (current)2 x (resistance)watts of power, and the power supply has to supply it.-- If there's a circuit with some voltage connected to it and some current flowingthrough it, then the resistance of the circuit is (voltage)/(current) ohms, the partsin the circuit heat up and dissipate (voltage) x (current) watts of power, andthe power supply has to supply it.There's no such thing as "the power of a circuit". The power supply supplies thecircuit with some amount of power, the circuit either dissipates or radiates someamount of power, and the two amounts are equal.
