Charge is a conserved quantity. What you perceive as heat is the energy of the particles 1 flowing at the drift speed around a few millimeters per second. Heat from each resistor in a parallel circuit will be calculated as the product of the voltage the same for each and current different and inversely proportional to the resistances.
You should think of voltage as pressure and the charge as the fluid being pushed forward. Thus in a parallel circuit if the voltages are not equal, changing the loops will violate this principle. Voltage is basically work done per unit charge and work is form of energy which has to be conserved. Card games. Why is voltmeter always connected in parallel with a circuit element across which voltage is to be measured? Why voltmeter is connected in parallel with the load resistance?
Why voltmeter is connected in parallel Quora? What happens if voltmeter is connected in parallel? Why is an ammeter connected in parallel? What happens if ammeter is connected in parallel? Why is voltmeter a high resistance device? What if ammeter is connected in parallel?
Why ammeter should not be connected in parallel? The primary reason that power is transmitted at high voltages is to increase efficiency. The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also.

Ben Davis April 20, Why must a voltmeter be connected in parallel with a resistor? Why do we need to connect the meter probes in series with the resistor and not across the resistor when measuring current? Why voltmeter is connected in parallel and ammeter is connected in series? Can you electrocute yourself with a multimeter? What can damage a multimeter?
Can a multimeter kill you? How do you reset a multimeter? Can a multimeter explode? How do you test if a cable is live with a multimeter? How do I know if my multimeter is bad? What does DCA stand for on a multimeter? What does m mean on a multimeter? What does counts mean on a multimeter? What are the different symbols on a multimeter? What is the symbol for current? What is the AMP symbol on a multimeter? Which is dangerous AC or DC? The devices cannot be connected to a voltage source because ammeters are designed to work under minimal burden.
Burden refers to the voltage drop across the ammeter, normally a very small fraction of a volt. The galvanometer is an instrument that measures current flow using the movement or deflection of a needle, which is produced by a magnetic force acting on a wire that current flows through.
The galvanometer is the heart of most analog meters. An analog voltmeter uses a pointer that moves across a scale according to the level of voltage and a digital would display a number.
