The current in a circuit is governed by voltage and resistance, as dictated by Ohm's Law. The voltage-current relationship can be linear in ohmic materials or nonlinear in non-ohmic materials.
The current flowing in a circuit depends primarily on two variables: voltage and resistance. This relationship is defined through Ohm's Law, which states that the current (I) in a circuit is equal to the voltage (V) divided by the resistance (R), or I=V/R.
When the voltage increases while the resistance remains constant, the current will increase. Conversely, when the resistance increases while the voltage remains constant, the current will decrease. Thus, for example, if the resistance doubles, the current is cut in half.
However, it is important to note that not all materials follow this linear relationship. Some materials, known as ohmic materials, follow Ohm's Law, while others, known as non-ohmic materials, exhibit a nonlinear voltage-current relationship.

Answer:
Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus.
Explanation:
Answer:
Yes
Explanation:
The higher the electronegativity the higher tendency to attract electrons, the lower the electronegativity the higher tendency to give away electrons/lose electrons.
b. beta decay
c. alpha decay
d. isotope number
The correct answer is option 2. One way of expressing concentration is by expressing it by parts per million or ppm. It is calculated by dividing the grams of solute and the grams of the solution, and the result is multiplied by 1 000 000. Parts per million is equal to 1 milligram of solute per kilogram of solution.
Answer:
Cp= 1.005 kJ/kg °C = 1.005 kJ/(kg*K) = 1.005 J/g°C = 4.206 J/g°C = 0.776 BTU/lb°F
Explanation:
for the specific heat
1) Cp= 1.005 kJ/kg °C * (1 °C/ 1 K) (temperature differences) = 1.005 kJ/(kg*K)
2) Cp= 1.005 kJ/kg °C * (1000 J/ kJ)* (1 kg/1000 gr) = 1.005 J/g°C
3) Cp= 1.005 kJ/kg °C * (4.186 kcal/kJ) = 4.206 J/g°C
4) Cp= 1.005 kJ/kg °C * (1 BTU/1.055 kJ)* (0.4535 kg/lb)*(1.8°C/°F)= 0.776 BTU/lb°F
