Define voltage current and resistance?
Voltage is the electrical pressure in a circuit Amperes (amps) are the measure of electrical current in a circuit Ohms are the measurements of resistance in a circuit Current is essentially how fast electrons are moving in a circuit Resistance is what impedes the electrical current, and can be found in the wire or various loads in a circuit Hope this helps!

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.
What happens to the voltage in a series circuit when more loads are added?
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.
What are the advantages of parallel connection?
parallel connection increases the current at constant voltage at the supply end & decreases the current flowing across the load. Answer Any load will only operate at its rated power when subjected to its rated voltage. As each branch of a parallel circuit is subject to a common voltage, this enables individual loads to operate at their rated power. This is the primary advantage of a parallel circuit. A secondary advantage is that (unlike a series circuit) if one load should open circuit, then the remaining loads will continue to operate normally.
Why the voltage same in parallel form?
In a parallel circuit, two or more loads are connected across a voltage. As the voltage is common to all loads, they will each have the same potential difference across them. The current through each load will vary according to the resistance of the load. Note that adding or removing one of the loads does not alter the voltage across the remaining loads, nor does it alter the currents through each of the remaining loads. It does vary the total current. This is different to a series circuit where two or more resistors are connected one after the other. In this case, the current through each one is identical. The voltage across each of the resistors will vary depending on the value of the resistor. The higher the resistance, the higher the voltage across that resistor. As a resistor reduces in value, so the voltage across that resistor will also reduce. Note that the total voltage across all resistors will be equal to the voltage supplied.
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. Answer Electric 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 is voltage always same in a parallel circuit?
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.

Asked in Electricity and Magnetism
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 to the current when the voltage stays the same in a circuit and more loads are added?
Ohm's Law says Voltage = Current x Resistance With constant voltage, an increase in resistance decreases the current. Now the load can be added in two basic ways. If the load is added in series the resistance will increase. If you add load in parallel the resistance will decrease and the current will increase from the source.
What is the relationship between current and voltage in a circuit?
V=IR V-voltage I- current R- resistance offered by the circuit board (can me measured using miltumeter) Answer The ratio of voltage to current is called resistance. If this ratio is constant for changes in voltage, then the circuit is described as being 'linear' or 'ohmic', and it obeys Ohm's Law. If this ratio varies for changes in voltage, then the circuit is described as being 'non-linear' or 'non-ohmic', and it does not obey Ohm's Law. Most loads and electronc devices are non-ohmic -that is their resistance varies with changes in voltage- which confirms that Ohm's Law is not a universal law, but one that applies only to certain types of load and, then, under specific conditions.

Asked in Electronics Engineering
What trouble that exist in parallel circuit if one of the load in parallel circuit is shorted?
when loads are connected in parallel it means that they share common nodes at both the ends i-e voltage across all the loads is the same. when one of the load in such a circuit is shorted i-e its voltage is made zero volts, voltage across the other loads goes to zero because of parallel connection and they gets shorted also.
