It is not necessary for anything about them to be the same.
All that is necessary is that they create the desired equivalent resistor, having the correct resistance and power dissipation rating without overstressing either resistor.
What else can I help you with?
What happens if 3 resistors connected in parallel and one of the resistors is open circuited?
When one resistor in a parallel circuit is open-circuited, it effectively becomes an infinite resistance and no current flows through it. The total resistance of the parallel circuit increases, but the remaining resistors continue to function normally. The overall current through the circuit will decrease because the total current is now only dependent on the remaining active resistors. The voltage across all parallel resistors remains the same as before the open circuit occurred.
When batteries are connected in parallel what happened with their voltage?
The voltage remains the same.
When there are three cells in a circuit how would the ammeter change?
In a circuit with three cells, the ammeter reading will depend on how the cells are connected. If they are connected in series, the total voltage increases, which can lead to a higher current, assuming resistance remains constant. If they are connected in parallel, the voltage remains the same as a single cell, but the total current could increase due to the combined capacity of the cells. Therefore, the ammeter's reading will vary based on the configuration of the cells.
What happens to the current as the resistor approches infinty?
Most resistors are linear, or 'ohmic', devices -which means that they obey Ohm's Law. So the ratio of voltage to current remains constant for variations in voltage. In other words, their resistance remains constant -providing their power rating isn't exceeded. So you can say that, providing the current increase doesn't cause their power rating to be exceeded, their resistance should remain the same. Resistors wouldn't be of much use if their resistance value changed whenever the current through them changed!
What is the name given to devices whose resistance remains constant as current increases?
Devices whose resistance remains constant as current increases are called "ohmic devices" or "ohmic resistors." These devices follow Ohm's Law, which states that the voltage across the device is directly proportional to the current flowing through it, maintaining a constant resistance regardless of the current levels. Examples include metallic conductors like copper and aluminum at moderate temperatures.
What term remains the same across all the resistances in a parallel combination of resistances?
The voltage across the resistors will remain constant.
What happens to supply voltage if additional resistance is connected in parallel circuit?
The supply voltage in a parallel circuit remains the same regardless of the number of additional resistors connected. The voltage across each resistor in a parallel circuit is the same as the supply voltage. Adding more resistors in parallel will increase the total current drawn from the supply.
How do you find resistance in a parallel circuit?
resistance inparallel decrease in value proportionally two resistance can be calculated as R1XR2/SUM OF R1+R2. many values can be calculated as a fraction 1/r+1/r2+1/3 ....and take the total sum reciprocal

What remains constant in series circuit?
A: No matter how many resistor of different value are inserted the current will remain the same for each. The voltage drop will vary with the difference in resistors and i a parallel path is found along the way the current will divide according to the resistors values
What will happen to voltage in a parallel circuit?
In a parallel circuit the voltage across each component is the same.
What is the total voltage of batteries connected in parallel?
When batteries are connected in parallel, the total voltage remains the same as the voltage of a single battery.
What quantity varies place to place in a parallel circuit?
In a parallel circuit, the current flowing through each branch varies from place to place because the total current splits up and takes different paths. Voltage remains the same across all branches in a parallel circuit.
What is the hypothesis for parallel circuits?
In a parallel circuit, the hypothesis is that when components are connected in parallel, the total current flowing into the junction equals the total current flowing out. Essentially, the hypothesis states that the total current remains constant regardless of the number of parallel paths.
What is the voltage when batteries are connected in parallel?
When placing voltage sources in parallel, the total voltage is the same as the individual battery's voltages. For example: If I was to place 4 "AA" 1.5 volt batteries in parallel with a life of x hours, the out put would be 1.5 volts with a life of 4x hours. note: never place batteries in parallel that are not in the same condition (charge, voltage, ect...).
When batteries are connected in parallel what happened with their voltage?
The voltage remains the same.
Name that line lines that always have the same distance between them?
parallel lines - they are parallel when the distance between them remains constant
