What else can I help you with?
How do you draw this you have three 20 ohm resistors available. how would you connect these three resistors to produce a 30 ohm equivalent you must use all three resistors?
You can achieve a 30 ohm equivalent resistance by connecting the resistors in a combination of series and parallel. Connect two resistors in series to get 40 ohms, then connect the third resistor in parallel with this combination to achieve a total resistance of 30 ohms.
What did ohm discover about thr relationship between these three factors currentvoltageandresistance?
The law named after him is: V = IR (in words: voltage = current x resistance) It is more intuitive if you express it solved for current, since current can be thought of as the dependent variable: I = V/R This shows that more voltage will result in more current, while more resistance will result in less current. Of course, in the SI the units are chosen in such a way that the proportionality constant is one (and doesn't appear in the equation).
A 5 ohm resistor a 10 ohm resistor and a 15 ohm resistor are connected in series to a 120 volt power source What is the amount of current flowing between the 5 ohm resistor and the 10 ohm resistor?
3.0 or threeAnswerIt depends how they are connected.In series, ther total resistance will be 220 ohms and, so, the current will be 120/220 = 0.545 A.In parallel, ther total resistance will be 20 ohms and, so, the current will be 120/20 = 6 A.
Who is physicist ohm?
Physicist Ohm refers to Georg Simon Ohm, a German physicist and mathematician who is best known for Ohm's Law, which relates the voltage, current, and resistance in an electrical circuit. Ohm's work laid the foundation for the development of the field of electrical circuit theory and helped in understanding the relationship between these fundamental electrical quantities.
What is the breakdown of the ohm units?
The ohm unit measures electrical resistance. It is represented by the symbol . The breakdown of the ohm unit is as follows: 1 ohm is equal to 1 volt per ampere. This means that if a voltage of 1 volt is applied across a circuit and it produces a current of 1 ampere, then the resistance of the circuit is 1 ohm.
What relationships did ohm discover between the three factors?
Ohm detected the following one V = R * I Here V is the potential difference across a conductor. R- resistance of the conductor and I is the current that flow through the conductor.
What are three related electrical factors did George Ohm investigate?
the answer is current, voltage, and resistance
Who discover the ohms law?
George Ohm, a German physicist.
How can three resistors of 2 ohm 3 ohm and 4 ohm be connected to give a total resistance of 4 ohm?
2 in series with 3&4 in parallel
What are the Contribution and discovery of george Simon ohm in electricity?
By discover of magnetic field hoped we helped
Can you use three 8 ohm speakers with one amplifier?
If the amplifier is designed for an 8 ohm load, then you should use an 8 ohm load. Three 8 ohm speaker in series is 24 ohms, and in parallel they are 2.67 ohms. Neither of those is a good match for an 8 ohm rated amplifier. If you do this, you will not achieve rated power, and you may well damage the amplifier.
What relation dod goere ohm discover between voltage current and resistance?
Ohm discovered that, for some conductors, the current flowing through the conductor is directly proportional to the potential difference across them. This does not apply to allconductors -in fact, it applies to very few. Ohm's Lawstates that 'the current flowing in a wire is directly proportional to the potential difference across that wire, providing its temperature (as well as other factors) remains constant'.Ohm's Law makes no mention of resistance. The equation, R= V/I is derived from the definition of the ohm, and not from Ohm's Law, and applies whether Ohm's Law is followed or not. For Ohm's Law to apply, there must be a linear relationship between the ratio of V:I . Those materials that obey this rule are called 'ohmic' or 'linear', while those that do not obey this rule are called 'non-ohmic' or 'non-linear' -most materials are 'non-ohmic'.
Who is Ohm and what did he discover?
Georg Simon Ohm was a German schoolmaster who discovered that for certain conductors, the ratio of voltage to current was constant for variations in voltage. He thought that this applied to all conductors, but this is not the case. In fact, Ohm's Law applies to very few conductors and, then, only under very specific conditions.

A 120 ohm resistor a 60 ohm resistor and a 40 ohm resistor are connected in parallel to a 120 volt power source What is the effective resistance of the three esistors?
The effective resistance of three resistors, 120 ohm, 60 ohm, and 40 ohm, in parallel is 20 ohms.RP = 1 / sum (1 / RN)RP = 1 / (1 / 120 + 1 / 60 + 1 / 40)RP = 20The voltage applied, 120V, does not change the outcome. The power, however, of the three resistors is 120W, 240W, and 360W respectively. This is a lot of power, so please do not attempt to do it for real.
What is the ohm's triangle?
V/IXR This helps you to remember the three versions of Ohm's Law: V = I X R R = V/I I = V/R
