Why is it dangerous to pass to much current through the mains cable?
Current or AMPS are what the appliance draws or load of the appliance. So, if you have a say 10,000 amps going thru a cable rated for say 1,000 amps , guess what ,the cable over heats and either will melt or at least catch fire.
How will the armature current and the output power of a dc shunt motors change with increasing load?
With increasing torque load the armature tends to slow down; the motor draws more current to compensate, and if there is armature resistance the back emf generated by the armature falls to allow the increased current to flow, which causes the motor to settle at a lower speed. The mechanical output power is the speed times the torque, and increasing the torque increases the power output provided the speed does not drop much.
Why is the base current in a transistor so much less than the collector current?
as the base current is very small compared to the emitter current,the collector current is nearly equal to the emitter current..
How much of the current is drawn if an appliance is plugged and switched off?
None
What is the difference between an earth fault relay and an over current relay?
earth fault relay is also a type of over current relay but the set value of current or relay sensing current is much less than the maximum load current.in over current relay relay sensing current ise than maximum load current mor
Is a crunch amp a good amp?
No, they overheat and chip out a draws too much current.
Why does my home AC charger charge my iPhone so much faster than my automobile DC charger?
Phone will charge faster with a larger charging current. Charging current depends on voltage, so your home charger likely has a higher voltage and therefore a higher charging current.
Does leaving on an iPod touch while charging affect the iPod?
no charging it while on is the same as while off the only thing different is maybe one or two apps won't work while charging and you can't move too much do to the short charger for ipods
If electric heater works on 115 V and draws 3 A of current how much power does it use?
The formula you are looking for is W = I x E.
What happens to your usb cord when you use it while charging your phone?
If you are charging your device on a laptop or desktop, your charge time will be much slower. From a wall plug, it will be faster.
Why does your motorcycle battery overheat while riding?
Pretty much for one of two reasons: Too much current going in, or too much current going out. That is, something faulty is draining it savagely when you ride, or - most of the time - your charging voltage regulator is not working properly and it's overcharging the battery. If you have a multimeter handy, measure the voltage across the battery when the engine is running, somewhat revved. If it's more than 13.5...14 Volts, you've got a charging problem...
How much does it cost to replace catalytic converter on a subaru legacy?
I have a 2005 legacy and the dealer is charging $1296, while another smaller repair place is charging $950.
How much power is used by an ultrasonic jewelry cleaner that draws 0.042 a of current from a 120 v line?
Power = (voltage) x (current) = (120) x (0.042) = 5.04 watts
How much power is used by a 120-V car battery that draws 0.5 A of current?
Cars do not have 120 volt batteries. They are 12 volt DC.
How much power is used by a 6 Volt battery that draws 0.5 A of current?
Power = Potential Difference (Voltage) x Current So in this case, Power = 6 x 0.5 = 3 watts
How many minutes does a 900mah battery run?
It depends on how much current is being drawn. If your device draws 1 milli-amp of energy, it will run for 900 hours. If your device draws 450 milliamps (mA) of energy it will run for 2 hours.
How much units current take to run table fans?
It depends on the wattage the fan draws. A simple way to work it out is to use a simple formula. Find where it tells you the wattage and then devide by the house hold voltage and that will give you how much current is being used in amps
