How do you connect 3x12v solar panels to become 24v?
You don't. 2 12v panels together don't make 24v - doesn't work that way. If you need 24v you need to get 24v panels.
How do you Calculate the contact rating of relay for AC and DC?
On the side of the relay there is a name plate that tells you the current carrying capacity of the contacts. It gives you the ratings at different AC voltages and a DC rating of the contacts at different voltages.
What is meant by swin burn test in dc shunt generator?
in swin burn test we find out the copar loses & iron loses of the dc generator
Theory for load test on dc shunt generator?
load test on dc shunt generator is a test to plot the internal and external characteristics of the generator.
What type of voltage applied during megger test?
DC
Can you connect a 24v dc motor to household current?
You need a DC power supply in order to connect a 24v DC motor to household power.
How do you convert 24volts to 12 volts?
If you want to convert 24v AC into 12v Ac, it's simple. Just get a transformer to convert 24 volts into 12 volts. This is called a stepdown transformer. If you want to convert 24v DC into 12v DC, it's more complicated. First you have to change the 24v DC into 24v AC by a switching converter that changes DC into AC. Then you would use a stepdown transformer as in the former example. Once the 24v AC is converted to 12v AC, then you use a rectifier bridge to change the 12v AC into 12v DC.
When you short two wires of 24V dc there is no sparking in telephone lines why?
because it dc not ac
What is the range of circuit breaker that can be used for a 24V DC equipment?
Use a fuse
What is the required input and output voltages for a personal computer to power on?
input 220v ac & output 24v dc
What types of magnet either permanent or electromagnetic for AC or DC relay?
What types of magnet either permanent or electromagnetic for AC and DC relay?"how DPDT relay works?
What does dc stand for in the dc test?
The DC Test was a test which students could take when applying for a Diploma course in nursing. The initials DC stood for Dennis Child, the test's creator.
1000w 24v dc is equal to how many watt in 230V AC?
The wattage would stay the same. It is the amperage that would change.
Ac relay and DC relay?
what is the meaning of ac relay and dc relay EDIT: a DC relay is simply a coil and core that pulls on an armature. An AC relay usually needs a shaded-pole core (couple of copper loops) to prevent the armature from vibrating at 60 cycles or so. The core, also, is laminated steel like a transformer; so is the armature to help contain the magnetic field. You should not substitute a DC rated relay for an AC , but the reverse should be ok, if voltage and current ratings are the same.
How do you power a 24v dc solenoid with a 4v battery?
You don't. The solenoid's voltage rating means that it needs that much voltage to operate correctly.
What size fuse will protect a dc relay with 170 ma?
If this is for your volvo pre round 3 test it's 1 amp. 170 ma is .17 amps.
What does DC stand for in DC test?
