What would happen to the voltage the battery delivers to the resistor if a transformer is used, as shown in the diagram? Multiple Cholce es It would Increase the voltage It would decrease the voltage nothing < Prev 4 of 15 Next >

Q: Explain why a transformer works for AC currents but not for DC currents

A: transformer work only on ac supply because A transformer needs an alternating current that will…

Q: Can you please explain how you got =460 frot he reduced circuit?

A: 200 ohm , 300 ohm  and 600 ohm are in parallel configuration  therefore these resultant 1/R1=1/200 +…

Q: in a pure inductive circuit if the supply frequency is reduced to 1/2 the resistance will be

A:

Q: same quantity at each resistor

A: I series combination of resistors current  passing through each resistors is equal ,  potential…

Q: Which circuit element acts like a short circuit (a wire with a reactance of nearly 0) as the…

A: The capacitive reactance is given by:Xc=1(2πf)C........(1)where,f is the frequency of an AC…

Q: Why does a transformer require ac?

A: The working principle of a transformer is mutual induction.

Q: Why does AC power alternate ?

A: Ac power is defined as a flow of charge that exhibits a periodic change in direction. This is known…

Q: Could a series circuit that includes a capacitor serve the same purpose as a parallel circuit? How?…

A: Capacitor is a passive electronic component which is used to store and release electricity (…

Q: Please explain what happens when the efficiency of a transformer increases and when the percentage…

A: 1. A transformer is a device that transfers electrical energy from one circuit to another through…

Q: EXAMPLE 21-10 Cell phone charger. The charger for a cell phone contains a transformer that reduces…

A: GivenVoltage in Primary coil ,Vp=120 VVoltage of Secondary coil , Vs=5 VNumber of turn in secondary…
