How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
What will happen when we change value of load resistance in transformer?
The secondary load current will change. This, in turn, will cause the primary current to change (the primary current being the phasor sum of the [IS (Np/Ns)] and the primary current (Io).
You are monitoring electric current in a circuit. you notice the voltage increasing this mean's that?
Ohm's Law states that the current (I) flowing in a circuit is directly proportional to the applied voltage (E) and inversely proportional to the circuit's resistance (R).I = E/RAnother way of stating Ohm's Law is that the applied voltage (E) is directly proportional to both the current (I) and the resistance (R).E = IxR.So, if the voltage (E) is increasing, then either:if you know the resistance (R) is staying constant then the current (I) must be increasing - which you would see because you are monitoring it! or, if the current (which you are monitoring) is actually staying constant, then, for the voltage to be able to increase:the circuit's resistance must be increasing orthe increasing voltage could be caused by a combination of both increasing current and increasing resistance!
How does loading effect affect flow of current?
Ohm's Law says that Voltage = Current x Resistance (Load). Therefore Current = Voltage / Resistance and as resistance decreases current increases and as resistance increases current decreases.
How do resistance behave in parallel circuit?
in a parallel circuit resistance decreases increasing the current.
How does the increasing the resistance affect the current?
Increasing resistance decreases current.
Do additional resistors affect current in a series circuit?
Yes, additional resistors affect current in a series circuit by increasing the total resistance, which decreases the total current.
How does increasing the number of cells in a parallel circuit affect the current?
by adding resistance in parallel more current is bound to flow
How can electric current be changed in Omh's Law?
Ohm's Law: V = IR Solving for current: I = V/R To affect the current, you can either change the voltage (more voltage --> more current), or the resistance (more resistance --> less current).
What does a variable resistor do and how does it affect the flow of electric current in a circuit?
A variable resistor is a component that can change its resistance value. By adjusting the resistance, it can control the flow of electric current in a circuit. Increasing the resistance reduces the current flow, while decreasing the resistance increases the current flow. This allows for precise control of the current in a circuit.
How does resistance affect a circuit?
Resistance in a circuit restricts the flow of electrical current, leading to a decrease in the overall current in the circuit. This results in a drop in voltage across the components in the circuit and the generation of heat as energy is dissipated due to the resistance. Increasing resistance can reduce the efficiency of the circuit by impacting the voltage and current levels.
What will happen when we change value of load resistance in transformer?
The secondary load current will change. This, in turn, will cause the primary current to change (the primary current being the phasor sum of the [IS (Np/Ns)] and the primary current (Io).
Would increasing the resistance increase electric current?
no
1 What is the effect caused by the ammeter resistance when an ammeter is inserted into a circuit to measure the current?
An ammeter has a finite resistance which is inserted in series with the rest of the circuit, increasing the total resistance and decreasing the current. A good ammeter has a very low resistance, so it shouldn't affect the circuit noticeably.
The amount of current in a circuit can what by increasing the amount of resistance present in the circuit?
No it cant. Voltage = Current x Resistance. So at constant Voltage if the Resistance is increased, Current will reduce
How does resistance affect the brightness of the bulb?
Increasing resistance in a circuit will decrease the current flowing through the bulb, resulting in reduced brightness. This is because the resistance restricts the flow of electrons and diminishes the amount of energy reaching the bulb to produce light.
