What else can I help you with?
A series LCR circuit consisting of R10 ohms and impedence 20 ohms is connected across an ac supply of 200 v rms The rms voltage across the capacitor is?
16.32 volts
Would cause a meter to read negative voltage across a dc motor?
A DC motor generates power when it is rotating even when no supply is connected.
What would happen if ammeter were connected directly across a voltage source?
An ammeter measures current by either being inserted in series with the load being measured or using a clamp-on device that induces a proportional current that the meter measures. Nothing should happen if you connect an ammeter across a voltage source unless it was very high voltage compared to the rating of the meter.
How does the number of bulbs affect the amount of electrisaty in a circuit?
Adding additional lamps has no effect on the supply voltage supplied to you home. If the lamps are connected in series, then the sum of voltage-drops appearing across each lamp will equal the supply voltage. If the lamps are connected in parallel, then the voltage across each lamp will equal the supply voltage.
When the dc motor is connected across an AC supply then?
It depends on the construction of the motor. If the field winding is connected in series with the armaturewinding, the motor is like a universal motor and will probably operate normally. If the field winding is connected in parallel with the armature, the motor will not run, but will draw current, make noise and get hot.
How do make a series circuit?
The components are not connected directly across the power supply. Instead they are 'daisy chained', the output of one leads into the input of the next.

How is the power factor meter connected?
power factor meters are connected across the supply
What does a inductor do when connected across ac supply?
opposes changes in current
What will happen if transformer are connected to dc supply?
It will get core saturation
What will happen if inductor connected with DC supply?
i think in case of dc supply there will not be any induction
What will happen if DC Fan connected to AC Supply?
The fan begins chattering or hamming.
What will be the resultant voltage across different voltage points connected in parallel?
The voltages appearing across each branch of a parallel circuit will be equal to the supply voltage.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
Why capacitor bank not connected across Diesel generator power supply?
I dont know.... may be due to save money
What is the amount of power consumed by a 60 watt 220 volt lamp when it is connected across 110 volt supply?
When connected to a 110-volt supply, the 60-watt 220-volt lamp will consume power that is calculated using the formula P = V^2 / R, where P is power, V is voltage, and R is resistance. Since the resistance of the lamp remains constant, the power consumption would be (110^2 / 220) = 55 watts. Thus, the lamp would consume 55 watts of power when connected across a 110-volt supply.
Why are capacitors parallel?
Capacitors are said to be connected together "in parallel" when both of their terminals are respectively connected to each terminal of the other capacitor or capacitors. The voltage (Vc ) connected across all the capacitors that are connected in parallel is THE SAME. Then,Capacitors in Parallel have a "common voltage" supply across them giving: VC1 = VC2 = VC3 = VAB = 12V
