∙ 13y agoThe effective resistance of two parallel resistances is (AB)/(A+B) =
(75 x 150) / (225) = 50 ohms.
Current = (Voltage) / (Resistance) = (150/50) = 3 Amperes.
Check, and more details:
Current through the 75-ohms = 150 / 75 = 2 Amp.
Current through the 150 ohms = 150 / 150 = 1 Amp.
Total current from the power supply = 2 + 1 = 3 Amp.
Notice that the power dissipated by the two circuit branches is
Through the light = E2/R = (150)2 / 75 = 300 watts.
Through the 'heater' = E2/R = (150)2 / 150 = 150 watts.
The light is a better heater than the heater is !
Heaters generally have low resistance.
In a parallel circuit, the lower resistance dissipates more power.
Electric furnaces and soldering guns have very low resistance.

How is a series circuit different to a parell circuit?
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
How parallel and series circuit different?
In a series circuit, current has to pass through each part of the circuit. In a parallel circuit, the current has several alternative paths.
What are the two ways in which a circuit may be arranged?
A circuit can be arranged in either a series or parallel configuration. In a series circuit, the components are connected in a single path, so the same current flows through each component. In a parallel circuit, the components are connected in multiple paths, allowing different currents to flow through each component.
What circuit is a circuit in which electrical current has more than one path to follow?
A circuit that has more than one path for the current to flow is a parallel circuit. The circuit must have two or more paths to be considered parallel. A circuit that has only one current path through multiple components is a series circuit.
Differentiate parallel circuit and siries circuit?
If two circuit elements (e.g., two resistors) are in series (a series circuit), the current has to pass first through one, then through the other. If they are in parallel, the current has a choice, through which of the elements it passes.
What is the iffrence between a series circuit and parallel circuit?
Series circuit: elements are connected one after the other; the current (the electrons, or other charge carriers) has to pass through each of the elements in turn. Parallel circuit: elements are connected in such a way that part of the current will pass through one circuit element, part through the other.
If I have a circuit with four lamps each lamp is individually connected across the circuit so that the same current is not flowing through each lamp What type of circuit is this?
Parallel Parallel
What is the difference between series and parallel circut?
If two or more circuit elements are connected in series, the current must pass through each of them in turn. If two or more circuit elements are connected in parallel, that means there is a "fork in the road". In this case, part of the current will pass through one element, and part, through another one.
How is a series circuit different to a parell circuit?
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
What are the multiple connected pathways through which electric current flows?
Integrated Circuit or Monolithic Integrated Circuit or IC is an electronic circuit set on a plate. Its microscopic pathways carries electrical currents.
Is a ammeter connected in series or in parallel with the circuit under test?
An ammeter is connected in series. A voltmeter is connected in parallel. ammeter should always be connected in series instead of parallel becoz it is a low resistance device and we know that resistance is inversly proportional to current so more current will pass through it and if it is connected in parallel than it may get damaged
How parallel and series circuit different?
In a series circuit, current has to pass through each part of the circuit. In a parallel circuit, the current has several alternative paths.
What is the difference between series circuit and parallel circiut?
AnswerA series circuit contanis only one circuit in which the current flows through.A parallel circuit contains two circuits, so the current flows through both and if one gap is made to the circuit, the other wire connected to the battery completes it.
What are the two ways in which a circuit may be arranged?
A circuit can be arranged in either a series or parallel configuration. In a series circuit, the components are connected in a single path, so the same current flows through each component. In a parallel circuit, the components are connected in multiple paths, allowing different currents to flow through each component.
Give the characteristics of a parallel circuit?
-- The voltage across every circuit element is the same, and is equal to the power supply voltage. -- The current through each circuit element is in inverse proportion to its impedance. -- The sum of the currents through all circuit elements is equal to the power supply current.
Why is it that the current flowing through a parallel circuit is the different in all parts of the circuit?
Because there is many path for flowing current through circuit.
Three 15 ohm resistors are connected in parallel to a 30 volt battery What is the current through each branch of the circuit?
2 amps
