What else can I help you with?
There are three sources of resistance in a parallel circuit. two of them are rated at 20 ohms the other at 10 ohms. what is the circuits total resistance?
5 ohms
What Effect does battery capacity on a circuits internal resistance?
Batteries are rated as ampere/hour any circuit that draws power from it effects it. The lower the internal resistance of the circuit the shorter the useful battery life as discharged.
Why is there less current in a circuit with four bulbs than there is in a circuit with one bulb?
yes because of bulb resistance :)
There are three sources of resistance in a parallel circuit two of them are rated at 20 ohms the other at 10 ohms what is the circuit's total resistances?
In a parallel circuit, the total resistance is calculated as the reciprocal of the sum of the reciprocals of each individual resistance. So, for three resistances of 20 ohms, 20 ohms, and 10 ohms, the total resistance will be 1 / (1/20 + 1/20 + 1/10) = 1 / (0.05 + 0.05 + 0.1) = 1 / 0.2 = 5 ohms.
There are three souces of resistance in a parallel circuit Two of them are rated at 20 ohm the other at 10 ohms What is the circuit's total resistance?
Three resistors in parallel: 20 ohms, 20 ohms, 10 ohms.1/ total resistance = (1/10) + (1/20) + (1/20) = (2/20) + (1/20) + (1/20) = 4/20 = 1/5 mho.Total resistance = 5 ohms
How do you increase resistance?
Since resistance is the ratio of voltage to current, if the voltage is constant then increasing the resistance will result in a reduction in current.
How would you connect meters in a circuit?
To connect meters in a circuit, it’s essential to determine whether you need to measure voltage, current, or resistance. For voltage measurements, connect the voltmeter in parallel across the component. For current measurements, connect the ammeter in series with the circuit component. Ensure the meters are rated for the circuit's voltage and current to avoid damage.
A fuse in a circuit is meant to burn out first if there is a short circuit. Should a fuse have a higher or lower resistance than the wire in the rest of the circuit?
The way current (series) fuses are designed and used, they are meant to overheat and blow and cause an open circuit if the current flow through these goes above the rated value. The resistance value typically is slightly higher than the wiring and adds marginal value of series resistance to the overall circuitry. The material characteristics of fuse ensure that at regular nominal current flow the fuse does not overheat, but when larger than expected current flows it overheats, melts (or gives very high resistance/open in a resettable fuse)and causes circuit to open.
What are the two types of overcurrent?
The two types of overcurrent are overload and short circuit. Overload occurs when the current flowing through a circuit exceeds its rated capacity for an extended period. Short circuit, on the other hand, happens when a direct connection is made between two points in a circuit with low resistance, causing a sudden spike in current flow.
Three soures of resistance in a parallel circuit two of them are rated at 20 ohms the other at 10 ohms what is the circuit total resistance?
The question appears to be describing three resistors all in parallel.The reciprocal of their net effective resistance is(1/20) + (1/20) + (1/10) = (2/20) + (1/10) = (1/10) + (1/10) = (2/10) = 1/5.The net effective resistance is [ 1 / (1/5) ] = 5 ohms.
What is short circuit ratio of an alternator?
Short circuit ratio is the ratio of field current required for the rated voltage at open circuit to the field current required for the rated armature current at short circuit
How many amps equal 1 circuit?
80% of the rated circuit. 10 amp circuit is 8 amps, 20 amp circuit is 16 amps, etc.
