What else can I help you with?
How can I describe how current varies with voltage in wires resistors metal filament lamps and diodes?
If it's DC voltage, the relationship between current, resistance and voltage is defined by Ohm's Law. V = I / R A little manipulation shows that I = V * R. If The voltage and/or resistance varies with time, an easy way to describe it would be thus: I(t) = V(t) * R(t) Where I(t), V(t) and R(t) are all functions of time.
Does the current remains the same in a series circuit despite the different values if the resistors in the circuit?
current in series depends on values of resistors. more resistance less current will flow through and viceversa
Do additional resistors affect power?
Of course. Additional resistors change total resistance, which changes current, which affects power.
How will amps and current differ in a series if you get resistors with different resistance?
-- "Amps" and "current" are the same thing. Electric current is measured in units of Amperes. -- The current is always the same at every point in a series circuit, no matter how many resistors of the same or different values are in the circuit.
What is true about series connections of resistors?
The more resistance there is, the harder it is for current to flow. So the total resistance is the sum of all resistors in series.
What is the relationship between resistors connected in series and the flow of current through them?
When resistors are connected in series, the flow of current through them is the same. This means that the current passing through each resistor is equal, as it has to pass through each resistor in the series circuit.
What are Relationship between the voltage drop across the resistors and the currents through the resistors when resistors are connected in parallel?
A: The relationship is that the current will divide for each paths in a parallel circuit and the voltage drop across each will be the source voltage. In a series circuit the current will remain the same for each component but the voltage will divide to reflect each different component value. And the sum of all of the voltage drops will add to the voltage source.
Do resistors resist voltage or current?
Resistors resist the flow of current in a circuit, not the voltage.
Describe the relation between the size of your source and electric current?
The current drawn from a power source is directly proportional to the voltage of thesource, and inversely proportional to the resistance of the circuit between its terminals.There is no relationship between the current and the physical size of the source.
Do resistors limit current or voltage in an electrical circuit?
Resistors limit the flow of current in an electrical circuit.
How is a circuit constructed with five resistors and a battery as shown?
A circuit with five resistors and a battery is constructed by connecting the resistors in series or parallel to create a closed loop for the flow of electric current from the battery through the resistors. The battery provides the energy for the current to flow through the resistors, which resist the flow of current. The arrangement of the resistors and the battery determines the overall resistance and current flow in the circuit.
What are resistors and why are they used?
Resistors are like funnels, they restrict the flow of current.
Why resistors are connecting?
resistors are used to resist the flow of current in a circuit.......
What is the relationship between capacitors in series and resistors in series?
resistor isdefined as the opposing the current flow in a circuit. capacitor is defined as the store the electric field in one forth of the cycle and the another quarter cycle stored energy will be released
What resistors do in circuts?
Resistors limit current. In an ideal circuit (theoretically impossible) the prevent current from becoming infinite.
Does the resistors current changes if the voltage across a fixed resistors is cut in half?
If the voltage across a resistor or resistors is halved, then the resulting current will also fall by half.
How can I describe how current varies with voltage in wires resistors metal filament lamps and diodes?
If it's DC voltage, the relationship between current, resistance and voltage is defined by Ohm's Law. V = I / R A little manipulation shows that I = V * R.
