If the 60 volts and the resistance of the load is 10 ohms the current is how many amperes?
6 amperes
Why use of capacitors to correct pf?
Power-factor improvement capacitors are connected in parallel with the load, and are rated in reactive volt amperes. If their reactive volt amperes are identical with the reactive volt amperes of the reactive component of the load, then they act to cancel each other, and bring the phase angle to zero (i.e. the load current becomes in phase with the supply voltage). This reduces the value of the load current without affecting the operation of the load, and allows cables and switchgear with lower current ratings to be used than would otherwise be necessary.
What is the significance of the diode load line in analyzing the operating point of a diode circuit?
The diode load line helps determine the operating point of a diode circuit by showing the possible combinations of voltage and current that the diode can have. This analysis is important for understanding how the diode will behave in the circuit and ensuring it operates within its specified parameters.
Can a diode work in ac?
A diode is a "one-way valve" that allows electrical current to flow in only one direction. A diode placed in series between an AC voltage source and a resistive load will allow current to flow through the load in one direction and block the current when the polarity of the AC voltage changes.
What KVA rating is required for a transformer that must handle a maximum load current of 8 Amperes with a secondary voltage of 2 kv?
The load is the product of the load current and the secondary voltage. So, in this example, the load is 8 x 2000 = 16 000 volt amperes, or 16 kVA. This must not exceed the transformer's rated kVA.
How long can it be expected to supply a current of 100mA if a cell supplies a load current of .5 amperes for a period of 20 hours?
100 hours.
What is the smallest load resistor that can be used and still maintain regulation in zener diode regulator?
The smallest load resistor that can be used while maintaining regulation in a zener diode regulator is determined by the zener diode's minimum load current (I_Z(min)) and the zener voltage (V_Z). The load resistor (R_L) must be calculated using Ohm's law, where R_L = V_Z / I_L, ensuring that I_L is at least equal to I_Z(min) to keep the zener in the breakdown region. If the load current falls below this threshold, the zener diode will not regulate the output voltage effectively.
What is kilo amperes?
The correct expression is 'kilovolt amperes' (kV.A), and it is a multiple the unit of measurement ('volt ampere') for the apparent power of a load in an a.c. circuit -i.e. the product of supply voltage and load current.
What is the full load current of 200kW 380V 3-phase generator with 0.8 lagging power factor?
304 Amperes
From theory you will remember that the zener diode is used in the?
Provided the zener has enough current through it it will control the voltage for a load.
Are motor conductors sized to the locked rotor current?
According to 2011 nfpa 70 nec Motor conductors are sized with the flc- full load current or the nameplate rating fla- full load amperes
What is the voltage across a load given that the current though it equals 30mA and resistance of the load is 1000 ohms?
Ohm's law: voltage is current times resistance 0.03 amperes times 1000 ohms = 30 volts.
