What happens to the voltage in a series circuit when more loads are added?
A: assuming a infinite current source the current will increase accordingly
What is meant by lagging and leading circuit?
The terms, 'lagging' and 'leading', describe the relationship between a circuit's load current and supply voltage. They describe whether the load current waveform is leading or lagging the supply voltage -always the current, never the voltage. Inductive loads always cause the current to lag the supply voltage, whereas capacitive loads always cause the current to lead the supply voltage.
Is electric circuit also called series circuit?
The 2 simplest Electrical circuits areSeries Circuit - Same amount of current running through loads but voltage various by the resistance of the loadsParallel Circuit - Same voltage on the different loads by subject to the load resistance, the current passing through is different
What device uses the voltage in an electrical current?
A voltage, or potential difference, is what causes current to flow through a circuit. So all devices (called 'loads') require a voltage applied to them.
What is the formula which defines the voltage drop across loads in a series circuit?
Ohm's Law says that the voltage drop is equal to the resistance of the loads times the current. It is written as V = I x R

Meaning or definition of voltage in a parallel circuit?
Voltage is the electrical potential that is produced by a given source (ie, a battery or a generator). The voltage is not changed by the type or number of loads on a circuit. A voltage regulator and/or transformer may change the voltage within a perticular load, but cannot change the complete circuit voltage.
What happens if you add more loads to a series circuit?
When you have multiple loads in a series, the resistance of the loads is added together allowing very little current to flow through the circuit to power any of the loads, making for a low amperage circuit. If you have your loads in parellel, the resistance of the loads in the circuit is subtracted which allows more current to flow, making for a high amperage circuit.
Is Voltage the same all parts of a series circuit?
Voltage is an electrical force or pressure that causes current to flow in a circuit. It is an additive in a series circuit.

Why is a current in a circuit never used up?
Kirchoff's Current Law: The signed sum of the currents entering a node is always zero. A consequence of this is that, for series circuits, the current at every point in the circuit is the same.If this does not answer the intended question, please restate the question and provide more information as to what, exactly, you are looking for. "Used up" is a vague and non-scientific term that does not entirely make sense.AnswerElectric current is not 'poured' into a circuit, like water from a kettle. Current is 'drawn' from the voltage supply by the load. It is a load that determines how much current is drawn for any given supply voltage. 'Heavier' loads (i.e. lower resistance loads) draw larger currents, while 'lower' loads (i.e. higher resistance loads) draw less current.
WHY does adding more loads in a parallel circuit increase the current?
Adding more loads in a parallel circuit increases the current because of Kirchoff's voltage and current laws, and because of Ohm's law...1. Kirchoff's voltage law states that the signed sum of the voltage drops around a series circuit is zero. A consequence of this is that the voltages across elements of a parallel circuit must be the same.2. Ohm's law states that current is voltage divided by resistance. Since the voltage across each new parallel element is the same, the current in that element is known. A consequence of this is that each additional element does not change the current in the other elements.3. Kirchoff's current law states that the signed sum of the currents entering a node is zero. A consequence of this, and 1 and 2 above, is that the currents added by each parallel element increases the total current entering the set of parallel elements.
