How did the current before the resistor compare with the current after?

Current flow would be the same through the resistor, since it's in series, but the voltage would be slightly reduced based on the resistance.
If you have 2 resistors in parallel, the current will divide through each resistor, and the voltage stays the same.

A can be used to reduce the current in a circuit?
A resistor.
Why a inductor is used in series before diode instead of resistor?
An inductor will supply better current source.
What is series dropping resistor?
A series dropping resistor is a resistor that limits the amount of current flow in a circuit.
Resistors A and B are connected in parallel If resistor B has twice the resistance of A what is the current taken by resistor B?
half of the current flowing thru resistor 1.... V=IR.
What component that makes it more difficult for current to flow?
IF there is a Resistor
Why is a resistor positioned before the transistor?
It is done in order to protect the transistor from the heavy currents flowing (resistor reduces current flow) into its terminals.
How do you install a resistor in an DC circuit?
It depends on the purpose for installing the resistor. If the intent is to decrease current flow, the resistor must be connected in series with the load. If the purpose is to increase current flow, the resistor must be connected in parallel with the load. To connect a resistor in series, connect the resistor to one side of the power source, in line with the load. This will decrease circuit current flow. To connect a resistor in parallel, connect the resistor between the positive and negative sides of the power source, which will effectively connect the resistor across the load . This will increase current flow through the circuit. However, before connecting a component in parallel, make sure the increase in current flow will not exceed the current rating of the circuit or fuses/breakers will blow.
A can be used to reduce the current in a circuit?
A resistor.
Is current is drop when it flowing through the resistor?
Current flows in loops, voltage drops across elements. With relation to current, what flows in, must flow out, so no, current is not dropped across a resistor, it flows through a resistor and voltage is dropped across the resistor.
What is a ballast resistor?
A ballast resistor is an electrical resistor whose resistance varies with the current passing through it, thus maintaining a constant current.
Why a inductor is used in series before diode instead of resistor?
An inductor will supply better current source.
What is the current drop across the resistor?
The correct question is what is the voltage drop across a resistor or the current flowing through the resistor using Ohm's Law where Voltage = Current x Resistance
Basic concept of resistor?
resistor is to resists the flow of current
Which is the Direction of the current in resistor?
A resistor is bi-directional meaning current can flow in either direction. Current flows from positive to negative.
Current divider rule?
Ix = IT(Rp/Rx+Rp) where Ix is the current you are trying to find, IT is the total current, Rx is the resistor in question, Rp is/are the resistor(s) in parallel with the resistor in question.
How do you find power generated in a resistor?
The power generated in a resistor is converted into heat. and that can be power which is converted into heat is the product of the voltage across the resistor and, current passing through the resistor. or the product of square of the current and the resistance offered by the resistor.
What the difference between Transistor and resistor?
The difference between a Transistor and a Resistor is that a transistor is designed to amplify the electrical current, whereas a Resistor is designed to reduce the electrical current.
