If you have a parallel circuit with a battery (4 ohms), a light bulb (2 ohm), and a fan (3 ohms), how would you find the total resistance of the circuit?
Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source. You can find total resistance in a Parallel circuit with the following formula: 1/Rt = 1/R1 + 1/R2 + 1/R3 +...
Answer:
resistance = 0.9230769230769231
Explanation:
The total resistance can be found by using the following equation:
1 / R = 1 / R1 + 1 / R2 + 1 / R3

What is uranium?Since more than 60 years ago, uranium, a heavy metal, has been employed as a plentiful source of concentrated energy. Uranium is as prevalent in the Earth's crust as tin, tungsten, and molybdenum, and it can be found in most rocks in quantities of 2 to 4 parts per million.
Seawater contains uranium, which may be extracted from the seas. German scientist Martin Klaproth made the discovery of uranium in the mineral pitchblende in 1789. Following the discovery of the planet Uranus eight years earlier, it was given that name.
In supernovae, uranium is thought to have been created around 6.6 billion years ago. Even though slow radioactive decay is uncommon in the solar system, it is the primary source of heat inside the Earth today, creating convection and continental drift.
Due to its great density, uranium is also used as radiation shielding, as counterweights for aviation control surfaces, and in boat keels. The melting point of uranium is 1132 °C. Uranium has the chemical symbol U.
Therefore the correct option is C.

Which of the following is true with regard to sodium and potassium?
A
The both have three outer shell electrons.
B
They both have filled orbitals.
C
They tend to form anions.
D
They tend to form cations.
Sodium and potassium tend to form cations. Therefore, the correct option is option D among all the given options.
What is ions?An atom or molecule is said to be an ion if a number of the valence electrons have been acquired or lost, providing it a net negative or positive electrical charge. In other terms, a chemical species has an unbalanced ratio of protons (positive charge particles) to electrons (negatively charged particles).
Because there are more protons than electrons in a given species, cations are ions with a net positive charge. The equation for a cation is denoted by a superscript that includes the amount of the charge and the symbol "+" after the formula. If present, a number comes before the plus sign. If there is simply a "+" there, the fee is +1. Sodium and potassium tend to form cations.
Therefore, the correct option is option D.
