The maximum secondary coil voltage is determined by the turns ratio between the primary and secondary coils in a transformer and the input voltage applied to the primary coil. It can be calculated using the formula: V_secondary = V_primary * (N_secondary / N_primary), where V is voltage and N is the number of turns in each coil.

In a transformer, the primary coil is the coil that has voltage applied to it. The secondary coil is the coil that we take voltage from. Transformers are used to step up voltage, step down voltage, or simply to isolate circuits.
I assume the primary has 12 volts applied. The voltage ratio from primary / secondary is equivalent to the turns ratio = 10/20, so the primary voltage is 1/2 of the secondary voltage. The secondary voltage is 24.
The output voltage in the secondary coil would be increased. Using the transformer formula Vp/Vs = Np/Ns (where Vp = primary voltage, Vs = secondary voltage, Np = number of turns in primary coil, Ns = number of turns in secondary coil), we can calculate the output voltage to be 160 volts (40V * 100/25).
The secondary voltage in a transformer is stepped up by having more turns in the secondary coil compared to the primary coil. This creates a higher electromagnetic induction which leads to a higher output voltage. The ratio of the number of turns in the primary coil to the number of turns in the secondary coil determines the degree of voltage stepping up.
The primary coil is the one with voltage applied, or the 'input'. The secondary coil is the one in which a voltage is induced by electromagnetism, or the 'output'. In a step up transformer, the secondary coil voltage is higher than the primary. In a step down transformer, the secondary coil voltage is lower than the primary. In an isolation transformer, the secondary coil voltage is the same as the primary. Here, the point of the transformer isn't to raise or lower voltage, but to keep a particular circuit electrically disconnected from another circuit, while still allowing the circuits to function together (through electromagnetism).
Transformers come in very many varieties and voltages. Transformers have ratings regarding the electrical power that they are connected to. The most important ratings are voltage, power and current. In general the insulation level and number of windings in the secondary and primary determine the maximum rated voltage, and the size of the magnetic wire that makes up the windings, and mass of the iron core, determines the rated power and rated current. It is the insulation level therefore, that determines the maximum, safe voltage that can occur on both the secondary side and the primary side. The turns ratio between the primary and secondary coils of the transformer determines the secondary voltage with respect to the primary voltage. If the primary coil has 1000 turns, and the secondary coil has 100 turns, the transformer turns ratio (usually designated by the letter "a") is 100 / 1000 = 0.1. If a = 0.1, then if 1000 volts are applied across the primary coil, ideally, 100 volts will be measured across the secondary. Transformers have been manufactured with secondary voltage ratings in the range of millivolts, to 1,000,000 volts.
