A simple circuit consists of a light bulb connected to the terminals of a battery. A voltmeter shows a potential difference of 1
larisa [96]
<h2>Answer:</h2>

38.14Ω

<h2>Explanation:</h2>

Let's solve this question using Ohm's law which states that the current (I) flowing through a conductor is directly proportional to the potential difference or voltage (V) across it. Mathematically;

V =  I R       -------------------(i)

<em>Where</em>;

R is the constant of proportionality called resistance of the conductor and is measured in Ohms (Ω)

<em>From the question;</em>

V = 18.5V

I = 0.485A

<em>Substitute these  values into equation (i) as follows;</em>

18.5 = 0.485 x R

<em>Solve for R;</em>

R = 18.5 / 0.485

R = 38.14Ω

Therefore the resistance of the bulb is 38.14Ω

A wire is connected to the ends of a 6v battery what is the potential difference between the ends of the wire and what is the cu
Tasya [4]

The potential difference between the ends of a wire is =6V

Ohm's Law says that I = E/R, current is voltage divided by resistance.

The voltage is not going to change.  The potential difference between the ends of the wire is 6.0 V for all three resistances.

let the resistance of the given wire is R

∴  according to the ohms law

The current is 6.0/R for each case.

Electric capability distinction, also called voltage, is the outside paintings needed to convey a rate from one location to another vicinity in an electric subject. Multiply the amount of the cutting-edge by using the amount of resistance in the circuit. The result of the multiplication could be the ability distinction, measured in volts.

Potential distinction are joules in keeping with coulomb, given the call volt (V) after Alessandro Volta. The familiar time period voltage is the commonplace call for electric potential difference. remember the fact that every time a voltage is quoted, it is understood to be the ability difference among two points.
