### 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 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.

###### Asked in Electronics Engineering, Physics, Electrical Engineering

### 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.

### 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.

###### Asked in Electrical Engineering, Electrical Wiring

### 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.
