When resistors are connected in series then what happens to the watt?
Resistors are rated in wattage so the lowest wattage rating will be the wattage of the series circuit. It will be able to handle that power any more and the lowest wattage resistor could be damaged and fail.Another AnswerWhen two or more resistors are connected in series, the resistor with the lowest resistance will operate at the highest power. If the power developed by a resistor exceeds its rated power, then the resistor may burn out.
Can more than one resistor be used in a circuit?
Yes, more than one resistor can be used in a circuit. Resistors can be connected in series, where their resistances add up, or in parallel, where the total resistance decreases. This allows for greater control over the current and voltage levels within the circuit, enabling designers to achieve desired electrical characteristics. Using multiple resistors can also help in managing heat dissipation and improving circuit functionality.
How to find Equivalent resistance when you have both parallel and series resistors?
To find equivalent resistance when you have both parallel and series resistors, start simple and expand... Find the smallest part of the circuit, such as a pair of resistors in series or a pair of resistors in parallel, and compute the equivalent single resistor value. Repeat that process, effectively covering more and more of the circuit, until you arrive at a single resistance that is equivalent to the circuit. For resistors in series: RTOTAL = R1 + R2 For resistors in parallel: RTOTAL = R1R2/(R1+R2)
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
How many resistors does a circuit diagram have?
The number of resistors in a circuit diagram can vary widely depending on the complexity of the circuit. A simple circuit may have just one or two resistors, while more complex circuits can have many, potentially dozens or even hundreds. The exact number is indicated in the specific circuit diagram being referenced. To determine the count, one would need to closely examine that diagram.
What are the differences between resistors connected in parallel and resistors connected in series, and how do these configurations affect the overall resistance in a circuit?
Resistors connected in parallel have the same voltage across them, while resistors connected in series have the same current passing through them. In a parallel configuration, the total resistance decreases as more resistors are added, while in a series configuration, the total resistance increases.
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.

What is two or more electrical components connected together called?
Two or more electrical components connected together is called a circuit. Depending on how components are connected, it is either an open circuit, closed circuit, or a short circuit.

How parallel resistors work?
Resistors in parallel work just like highway lanes in parallel. -- The more lanes there are, the more traffic they can carry. -- Any number of lanes in parallel are always wider than the widest single lane, and can carry more traffic than the widest single lane can. "wide lane" = low resistance "narrow lane" = "high resistance" "traffic" = "electric current"
What is the apparent rule for total resistance when resistors are added up in series?
The total resistance in a series circuit is simply the sum of the individual resistances of all the resistors connected in that series. This means that if you have multiple resistors, you add their resistance values together to find the total resistance. Mathematically, it can be expressed as ( R_{total} = R_1 + R_2 + R_3 + \ldots + R_n ). The total resistance increases as more resistors are added in series.
How do you reduce a line level audio signal to a mic level In a low impedance circuit?
To reduce a line level audio signal to mic level in a low impedance circuit, you can use a passive attenuator, such as a voltage divider, consisting of resistors. This involves selecting two resistors: one connected to the line level source and the other connected to ground. The output is taken from the junction of the two resistors, which effectively lowers the signal voltage to mic level. Alternatively, an active solution like a preamp can be used to match impedance and adjust the signal level more effectively.
What happens to the current in circuit as the resistance increases?
Current decreasesWhen voltage remains constant and resistance increases the current in the circuit will reduce.More informationV=IRwhere V is voltage,I is current andR is resistance.From the above equation,R=V/I, and hence resistance is indirectly proportional to current.Therefore, an increase in resistance would have the effect of decreased current.NB: this holds true only as long as the voltage remains constant.Another opinionHowever, this is only true in the case of a circuit connected in series.When circuits are connected in parallel, the opposite happens. If there is an increase in the amount of resistors in parallel, the total resistance of the circuit then decreases and the current increases subsequently.Yet another viewNo, that's not stated right.If more resistors are added in parallel - so that the circuit's overall total resistance decreases and its total current increases - that is NOT in any way the opposite of what this question is asking about...Let's make this crystal clear, so that there is no confusion: "an increase in the amount of resistors" is NOT the same as "an increase in resistance".So a parallel circuit behaves EXACTLY the same as a series circuit: if its overall resistance increases, the overall current going through the parallel circuit decreases AND if its overall resistance decreases, the overall current going through the parallel circuit increases.Actually, the second opinion is correctIn a parallel circuit, there are more branches to allow electrons back to the power supply, so current increases. With more resistors in a circuit, the overall resistance in a parallel circuit DECREASES.In a series circuit, current is the same throughout. So if more resistors are added, resistance INCREASES and so current DECREASES.
